text: " With a steadily increasing number of machines and devices
producing electromagnetic radiation, especially, sensitive instruments as well
as humans need to be shielded from electromagnetic interference (EMI). Since ideal
shielding materials should be lightweight, flexible, drapable, thin and inexpensive,
textile fabrics belong to the often-investigated candidates to meet these expectations.
Especially, electrospun nanofiber mats are of significant interest since they
can not only be produced relatively easily and cost efficiently, but they also
enable the embedding of functional nanoparticles in addition to thermal or chemical
post-treatments to reach the desired physical properties. This paper gives an
overview of recent advances in nanofiber mats for EMI shielding, discussing their
production, physical properties and typical characterization techniques.\r\n "

text: " Carbon nanofibers are used for a broad range of applications,
from nano-composites to energy storage devices. They are typically produced from
electrospun poly(acrylonitrile) nanofibers by thermal stabilization and carbonization.
The nanofiber mats are usually placed freely movable in an oven, which leads to
relaxation of internal stress within the nanofibers, making them thicker and shorter.
To preserve their pristine morphology they can be mechanically fixated, which
may cause the nanofibers to break. In a previous study, we demonstrated that sandwiching
the nanofiber mats between metal sheets retained their morphology during stabilization
and incipient carbonization at 500 °C. Here, we present a comparative study of
stainless steel, titanium, copper and silicon substrate sandwiches at carbonization
temperatures of 500 °C, 800 °C and 1200 °C. Helium ion microscopy revealed that
all metals mostly eliminated nanofiber deformation, whereas silicone achieved
the best results in this regard. The highest temperatures for which the metals
were shown to be applicable were 500 °C for silicon, 800 °C for stainless steel
and copper, and 1200 °C for titanium. Fourier transform infrared and Raman spectroscopy
revealed a higher degree of carbonization and increased crystallinity for higher
temperatures, which was shown to depend on the substrate material.\r\n "

text: " Polyacrylonitrile (PAN) nanofiber mats are typical precursors
for carbon nanofibers. They can be fixed or even elongated during stabilization
and subsequent carbonization to gain straight, mechanically robust carbon nanofibers.
These processes necessitate additional equipment or are—if the nanofiber mats
are just fixed at the edges—prone to resulting in the specimens breaking, due
to an uneven force distribution. Hence, we showed in a previous study that electrospinning
PAN on aluminum foils and stabilizing them fixed on these substrates, is a suitable
solution to keep the desired morphology after stabilization and incipient carbonization.
Here, we report on the influence of different metallic and semiconductor substrates
on the physical and chemical properties of the nanofiber mats after stabilization
and carbonization at temperatures up to 1200 °C. For stabilization on a metal
substrate, an optimum stabilization temperature of slightly above 240 °C was found,
approached with a heating rate of 0.25 K/min. Independent from the substrate material,
SEM images revealed less defect fibers in the nanofiber mats stabilized and incipiently
carbonized on a metal foil. Finally, high-temperature carbonization on different
substrates is shown to allow for producing metal/carbon nano-composites.\r\n "

text: " Electrospun poly(acrylonitrile) (PAN) nanofibers are typical
precursors of carbon nanofibers. During stabilization and carbonization, however,
the morphology of pristine PAN nanofibers is not retained if the as-spun nanofiber
mats are treated without an external mechanical force, since internal stress tends
to relax, causing the whole mats to shrink significantly, while the individual
fibers thicken and curl. Stretching the nanofiber mats during thermal treatment,
in contrast, can result in fractures due to inhomogeneous stress. Previous studies
have shown that stabilization and carbonization of PAN nanofibers electrospun
on an aluminum substrate are efficient methods to retain the fiber mat dimensions
without macroscopic cracks during heat treatment. In this work, we studied different
procedures of mechanical fixation via metallic substrates during thermal treatment.
The influence of the metallic substrate material as well as different methods
of double-sided covering of the fibers, i.e., sandwiching, were investigated.
The results revealed that sandwich configurations with double-sided metallic supports
not only facilitate optimal preservation of the original fiber morphology but
also significantly accelerate the carbonization process. It was found that unlike
regularly carbonized nanofibers, the metal supports allow complete deoxygenation
at low treatment temperature and that the obtained carbon nanofibers exhibit increased
crystallinity.\r\n "

text: Polyacrylonitrile (PAN) nanofibers, prepared by electrospinning, are
often used as a precursor for carbon nanofibers. The thermal carbonization process
necessitates a preceding oxidative stabilization, which is usually performed thermally,
i.e., by carefully heating the electrospun nanofibers in an oven. One of the typical
problems occurring during this process is a strong deformation of the fiber morphologies—the
fibers become thicker and shorter, and show partly undesired conglutinations.
This problem can be solved by stretching the nanofiber mat during thermal treatment,
which, on the other hand, can lead to breakage of the nanofiber mat. In a previous
study, we have shown that the electrospinning of PAN on aluminum foils and the
subsequent stabilization of this substrate is a simple method for retaining the
fiber morphology without breaking the nanofiber mat. Here, we report on the impact
of different aluminum foils on the physical and chemical properties of stabilized
PAN nanofibers mats, and on the following incipient carbonization process at a
temperature of max. 600 °C, i.e., below the melting temperature of aluminum.

text: Thermally stabilized and subsequently carbonized nanofibers are a
promising material for many technical applications in fields such as tissue engineering
or energy storage. They can be obtained from a variety of different polymer precursors
via electrospinning. While some methods have been tested for post-carbonization
doping of nanofibers with the desired ingredients, very little is known about
carbonization of blend nanofibers from two or more polymeric precursors. In this
paper, we report on the preparation, thermal treatment and resulting properties
of poly(acrylonitrile) (PAN)/poly(vinylidene fluoride) (PVDF) blend nanofibers
produced by wire-based electrospinning of binary polymer solutions. Using a wide
variety of spectroscopic, microscopic and thermal characterization methods, the
chemical and morphological transition during oxidative stabilization (280 °C)
and incipient carbonization (500 °C) was thoroughly investigated. Both PAN and
PVDF precursor polymers were detected and analyzed qualitatively and quantitatively
during all stages of thermal treatment. Compared to pure PAN nanofibers, the blend
nanofibers showed increased fiber diameters, strong reduction of undesired morphological
changes during oxidative stabilization and increased conductivity after carbonization.

text: Polyacrylonitrile belongs to the most often used precursors for carbon fibers.
Using electrospinning, polyacrylonitrile nanofiber mats can be prepared and afterwards
stabilized and carbonized to prepare carbon nanofiber mats which, by adding other
materials, will be useful for several applications. One of these materials is
TiO2, which has photocatalytic properties and can thus be used as a photocatalyst
for photodegradation of dyes. Here, we report on a detailed study of electrospinning,
stabilization, and carbonization of electrospun polyacrylonitrile/TiO2 mats with
varying TiO2 content. Depending on the amount of TiO2 in the nanofibers, the fiber
morphology changes strongly, indicating an upper limit for the preparation of
carbon/TiO2 nanofibers with smooth surface, but offering an even increased inner
surface of the rougher carbon/TiO2 nanofibers with increased TiO2 content due
to better maintenance of the fibrous structure during stabilization.

text: 'Electrospinning is a well-known technology used to create nanofiber mats
from diverse polymers and other materials. Due to their large surface-to-volume
ratio, such nanofiber mats are often applied as air or water filters. Especially
the latter, however, have to be mechanically highly stable, which is challenging
for common nanofiber mats. One of the approaches to overcome this problem is gluing
them on top of more rigid objects, integrating them in composites, or reinforcing
them using other technologies to avoid damage due to the water pressure. Here,
we suggest another solution. While direct 3D printing with the fused deposition
modeling (FDM) technique on macroscopic textile fabrics has been under examination
by several research groups for years, here we report on direct FDM printing on
nanofiber mats for the first time. We show that by choosing the proper height
of the printing nozzle above the nanofiber mat, printing is possible for raw polyacrylonitrile
(PAN) nanofiber mats, as well as for stabilized and even more brittle carbonized
material. Under these conditions, the adhesion between both parts of the composite
is high enough to prevent the nanofiber mat from being peeled off the 3D printed
polymer. Abrasion tests emphasize the significantly increased mechanical properties,
while contact angle examinations reveal a hydrophilicity between the original
values of the electrospun and the 3D printed materials. '
