Testing and characterization of binary and ternary blends with poly (lactic acid), acrylonitrile-butadiene-styrene and tapioca cassava starch powder

Abstract

In this research paper explores about biodegradable polymers such as Poly lactic acid (PLA), Acrylonitrile-Butadiene-Styrene (ABS) and Tapioca cassava starch powder (TCSP) and their blends prepared using conventional method. The prepared bio degradable polymer blends are analyzed with the help of Universal testing machine (UTM-3969), scanning electron microscopy (SEM).On the weight basis PLA, ABS, and TCSP are transferred into binary and ternary blends such as PLA, ABS, PLA/ABS, PLA/ABS/TCSP (wt.%) etc. are compared with various mechanical properties such as tensile stress v/s tensile strain, tensile strength v/s tensile module and compressive. The scanning electron microscopy images for tensile fractured samples showed smooth homogeneous finish and good partial distribution.
