Structure and properties of films based on blends of polyamide–polyhydroxybutyrate

Abstract

The structure and transport and diffusion properties of film matrices based on polyamide and polyhydroxybutyrate blends obtained from solutions and melts are studied. Quantitative analysis of the diffusion and sorption of water shows that the dependence of the diffusion mobility of water increases exponentially with increasing content of polyamide as the more hydrophilic component of the system. The developed materials are recommended for the creation of new therapeutic systems of controlled release of drugs.
