Current Progress on Biodegradable Materials Based on Plasticized Starch

摘要

This paper presents some current progress on biodegradable materials that are based on plasticized starch(PLS).To improve the hydrophobic character of the material for packaging applications,for example,a recent and promising development based on a PLS-biopolyester(e.g.polycaprolactone)blend with plasma-coated SiO_x is presented.PLS-biopolyester blends can show,under certain processing conditions,a pseudo-multilayer structure with a polyester skin that allows good adhesion of SiO_x deposits.XPS and FTIR-ATR determinations are used to assess the outer surface.
