Compatibility of L-Tyrosine Derived Biodegradable Polycarbonate/Chitosan Blends

Abstract:

In the present study, the compatibility and degradability of L-tyrosine derived polycarbonate(PC)/Chitosan（CTS）blend were investigated. The PC was synthesized in our laboratory. Blends of the polymers with compositions 4/1, 3/1, 1/1,1/3 and 1/4 w/w were prepared by solution-casting. The blends were characterized by FT-IR,DSC,XRD,SEM. No obvious two phases were observed. DSC and SEM analysis implied that all those components in consideration were compatible well in the blend formulation systems.Tg of the blends decreased with increasing PEG content. With the increase of the CTS content, the water retention ratio increases from 15% to 61%.
