The objective of this project was to investigate the effect that plasticizers had on starch and poly(lactic) acid blends. The type and ratio of plasticizers used was varied. Water, glycerol and citric acid were added to starch, which was plasticized and blended with PLA. After each step, the mixtures were characterized using DSC, GPC, SEM, IR spectroscopy and mechanical testing. It was determined that a 70/18/12 blend of starch/water/glycerol blended 50:50 with PLA had the best properties.
