Biodegradable Polymer /Clay Nanocomposites Based on Poly(Butylene Adipate-co-Terephthalate) and Poly(Lactic Acid)

摘要

Poly(butylene adipate-co-terphthalate) (PBAT) is a biodegradable polymer with high ultimate elongation but low modulus. This paper demonstrates that the addition of nano-sized clay can improve the modulus without significantly decreasing the tensile strength and biodegradability of the PBAT , while offering enhanced blendability with a rigid biodegradable polymer as a conceivable means to improve the PBAT's modulus.
