Abstract
The research aims to investigate the outcome of interaction of poly (lactic acid) with chemically treated sago starch at different weight percentages. Biodegradable polymer is one of the most promising alternatives to replace conventional petroleum-based polymers. Poly (lactic acid) is derived from renewable resources and many researchers had conduct studies to improve the mechanical properties of PLA biocomposite. PLA-based biocomposites are applied in industrial applications such as food packaging and biomedical. The limitation of PLA matrix such as poor mechanical properties and low thermal resistance can be improved by using chemically treated sago starch as biodegradable fillers. Sago starch are hydrophilic and polymer matric are hydrophobic. These two distinct nature forms weak covalent bond. To improve the properties, three different chemicals suggested for this research project. Three different types of chemical treatment which are grafting with acrylonitrile, grafting with benzenediazonium salt and with tetrahydrofuran. PLA matrix and chemically treated sago starch are mixed at different weight percentage by solvent casting method. The addition of biodegradable filler improve the mechanical properties of PLA based biocomposites. Morphological study, mechanical study, FTIR and thermal behavior characterization were carried out to analyze the specimen.
