Fabrication of Asymmetric Porous Hydrophilic Nanofiber Mat Using a Co-solvent Post-treatment Technology

초록

Nanofiber has been widely used for a variety of applications due to high mechanical strength as well as high porosity. For improvement of performance of each application, facile and cost-effect technologies have been developed to tune the structure and surface of nanofibers. In this study, asymmetric nanofiber mats were fabricated using a co-solvent post-treatment technology. First, polyethersulfone solutions of low concentrations were electrosprayed to fabricate particles, and then electrospun nanofibers were consequently deposited onto them. Using a co-solvent post-treatment technology, asymmetric porous nanofiber mats were simply fabricated by enhancing the adhesion among all the interconnection points among fibers as well as particles. Especially, when Pluronic F127 was dissolved in the co-solvent solution, it was facile fabricating asymmetric porous nanofiber mats with hydrophilic surface modification.
