Abstract

The present paper reports on the preparation of hybrid polymeric hydrogels consisting of poly(vinylalcohol) (PVA) and Chitosan (CHI) blends and relevant composites loaded with multiwalled carbon nanotubes (MWCNT). The hydrogels, prepared by the physical freeze-drying method were specifically characterized in the merit of their morphological, thermal and swelling/deswelling behavior. The obtained results indicate that PVA/CHI/MWCNTs hydrogel nanocomposites appear good candidates for biomedical and pharmaceutical applications. The presence of up to 0,5 % MWCNTs in the investigated polymeric hydrogel composites does not negatively affect the biocompatibility of the PVA/CHI hybrid polymeric blends used as continuous matrix.
