Abstract

Multifunctional nanofibers were fabricated by electrospinning of polyvinyl alcohol (PVA)/octadecylamine montmorillonite (ODA-MMT) layered silicate nanocomposite as a matrix polymer and amphiphilic copolymer-g-biopolymer (polylactic acid, PLA) as a biocompatible partner polymer.  PLA-grafted copolymer exhibited amorphous structure and improved processability due to internal plasticizing effect of lactic acid units. Crystal structure of the nanofibers significantly changed due to in situ phase separation processing via different chemical and physical interfacial interactions. Relative high thermal stability, high first melting and low crystallinity were observed for the matrix/polymer nanofibers. Nanofiber surfaces exhibit low cytotoxicity and necrotic effect for MC3T3 preosteoblast cells.
