Fabrication and Characterization of Polyvinyl Alcohol/Polyethylene GlycolNanofibers

Nanofibers based on polyvinyl alcohol (PVA) and polyethylene glycol (PEG) with differentparameters were produced as phase change fibers. According to experimental attempts the PVA andPEG ۱۰۰۰ concentrations and ratio of PVA:PEG was selected ۱۲% w/v, ۵۰% w/v and ۸:۲ respectivelyfor producing nanofibers. Also we used crosslinking material and initiator to create semiinterpenetrating semi-IPN structure to preventing solubability of polymers. Becasuse of more phasechanging properties the fatty acid ester was used in cor shell structure of nanofibers.
