Plastics from Starch and Poly(lactic acid) - KANSAS STATE UNIV
Project Methods Corn starch for industrial use, high amylose corn starch, and corn starch with a varying ratio of amylose and amylopectins will be used. PLA mainly from L-lactic acid will be used. This research plan has three major phases: Phase I (objective 1 to 3) will focus on the investigation of diblock formation, identification of plasticizers, and formulations at the lab-bench-scale by

The Ternary Blends of TPS/PBAT/PLA Films: A Study on the
This study investigated the effect of polylactic acid (PLA) on the mechanical properties and biodegradability of a ternary blend comprising of thermoplastic starch (TPS), Polybutylene adipate terephthalate (PBAT) and PLA. The binary blend (TPS/PBAT) and ternary blend (TPS/PBAT/PLA) with various contents of PLA were prepared through a twin-screw compounding using an intensive mixing
