Abstract

Abstract: The aim of the present study is to understand the effect of concentration of reinforcement and plasticizer on specific properties of the polymer matrix, by fabricating Poly lactic acid (PLA) based bio-composite. The bio-composite was prepared by solution casting method with PLA as the matrix, chloroform as the solvent, polyethylene glycol (PEG) as the plasticizer as well as compatibilizer, and microcrystalline cellulose (MCC) as the reinforcement. The degradation kinetics of PLA based composites was determined using the Coats-Redfern equation over a range of 1-5 wt % of MCC. Fabricated PLA based composites were evaluated for thermal stability, and morphology
