Conducting polyaniline with o-aminobenzenesulfonic acid copolymer (PAni-co-PABSA) and poly (vinyl alcohol) (PVA)/chitosan oligossacaride (COS) biopolymers based electrospun nanofiber membranes have been exploited for wound healing applications. The nanofiber membranes were assembled by generating two full-thickness skin wounds on the dorsum of SD rats. The PAni-co-PABSA/PVA/COS nanofiber membranes treated wounds show much smaller inflammatory reactions throughout the experimental period.

The present study is focused on the preparation of chitosan (CS)/polyacrylonitrile (PAN) blend and semi-interpenetrating polymer network (sIPN) hydrogel films, and their application to the adsorption of Rhodamine B dye. The CS/PAN blend hydrogel films were prepared by solution casting technique. To prepare sIPN, CS was cross-linked with epichlorohydrin (ECH). The developed CS/PAN blends and sIPN hydrogels were characterized with field emission scanning electron microscope (FESEM) and Fourier transform infrared (FT-IR) spectroscope.

The present study is focused on the preparation of chitosan (CS)/polyacrylonitrile (PAN) blend and semi-interpenetrating polymer network (sIPN). Blend CS/PAN hydrogel films (HFs) were prepared by solution blending and casting technique. CS in the blend was crosslinked with epichlorohydrin (ECH) to prepare sIPN.
