Effect of volume plasticizers on the thermal performance of Tacca leontopetaloides Starch Biopolymer

摘要

The effect of 10, 30 and 50 % volume of Olein oil, Glycerol and Crude Palm Oil (CPO) as plasticizer on the thermal performance of biopolymer has been investigated in this paper. The biopolymer was developed from a new source of starch, Tacca leontopetaloides, and natural rubber by using two roll-mill. Changes in functional groups and thermal performance of formulated bio-Thermoplastic elastomer (TPE) were analyzed by Fourier Transform Infrared (FTIR) and Thermogravimetric Analyzer (TGA). Increased volume of Olein oil and glycerol resulted to increasing strength of hydrogen bonding in the intermolecular TPEs, therefore it has high thermal resistant towards high temperature. Conversely, increased volume of CPO decreased the strength of hydrogen bonding in structural starch and CPO therefore TPE with CPO shows high degradability which possess up to 100 % weight reduction at 500 °C.
