--- res: bibo_abstract: - Electrospinning is a frequently used method to prepare air and water filters. Electrospun nanofiber mats can have very small pores, allowing for filtering of even the smallest particles or molecules. In addition, their high surface-to-volume ratio allows for the integration of materials which may additionally treat the filtered material through photo-degradation, possess antimicrobial properties, etc., thus enhancing their applicability. However, the fine nanofiber mats are prone to mechanical damage. Possible solutions include reinforcement by embedding them in composites or gluing them onto layers that are more mechanically stable. In a previous study, we showed that it is generally possible to stabilize electrospun nanofiber mats by 3D printing rigid polymer layers onto them. Since this procedure is not technically easy and needs some experience to avoid delamination as well as damaging the nanofiber mat by the hot nozzle, here we report on the reversed technique (i.e., first 3D printing a rigid scaffold and subsequently electrospinning the nanofiber mat on top of it). We show that, although the adhesion between both materials is insufficient in the case of a common rigid printing polymer, nanofiber mats show strong adhesion to 3D printed scaffolds from thermoplastic polyurethane (TPU). This paves the way to a second approach of combining 3D printing and electrospinning in order to prepare mechanically stable filters with a nanofibrous surface.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Tomasz foaf_name: Kozior, Tomasz foaf_surname: Kozior - foaf_Person: foaf_givenName: Al foaf_name: Mamun, Al foaf_surname: Mamun - foaf_Person: foaf_givenName: Marah foaf_name: Trabelsi, Marah foaf_surname: Trabelsi - foaf_Person: foaf_givenName: Martin foaf_name: Wortmann, Martin foaf_surname: Wortmann - foaf_Person: foaf_givenName: Sabantina foaf_name: Lilia, Sabantina foaf_surname: Lilia - foaf_Person: foaf_givenName: Andrea foaf_name: Ehrmann, Andrea foaf_surname: Ehrmann bibo_doi: 10.3390/polym11122034 bibo_issue: '12' bibo_volume: 11 dct_date: 2019^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/2073-4360 dct_language: eng dct_subject: - electrospinning - 3D printing - FDM printing - nanofiber mat - adhesion - water filter dct_title: Electrospinning on 3D Printed Polymers for Mechanically Stabilized Filter Composites@ ...
