摘要

LLDPE-Starch blend polymer has already found to be a potential to replace non-degradable plastic however, the degradation of that polymer in natural ambience (Soil burial test) needs to be further evaluated. The purpose of this study is to investigate the degradability of LLDPE starch blend polymer is soil medium. Thermoplastic starch as Native potato starch used and it's physically modified by different modifier such as Glycerol, Sorbitol & Urea. The behavior of thermoplastic produced was investigated in the processing and thermal, mechanical and morphological characterization. The addition of TPS reduced mechanical strength and also increased the biodegradation property. The TPS/LLDPE blend exhibit good mechanical strength up to 5% to 15% starch loading, after 15% loading there was a significant decrement change in mechanical behavior. The mechanical strength decrement proportion all to TPS percentile increment. Thermo-gravimetric analysis represented the decomposition behavior and Therefore degradation of plastic is an important issue for environment and economic reasons. Blending has become versatile route to obtain polymer with wide range of desirable properties. In order ensure homogeneity in the blends at microscopic level. It is necessary to reduce the interfacial tension, so that the characteristics of the blend component are improved or at least retained. Scanning electronic microscopy investigated the surface morphology and improved that the soil burial tests for biodisintegrable properties. Before degradation pictures proved that the dispersion of TPS molecules in LLDPE is the best.
