Abstract:
The present research focuses on the development of compounding of poly (lactic acid) (PLA) for plastic bags by exploring the additives to be chosen i.e., plasticizer : poly (butylene succinate adipate) (PBSA), glycerol, polyethylene glycol (PEG) 200, PEG 6,000, PEG 20,000, nucleating agent: talc, cloisite Na+, polyoxymethylene, succinic acid, filler: tapioca starch, compatibilizer: maleic anhydride, 3-glycidoxypropyltrimethoxysilance, methylenedi-p-phenyl diisocyanate (MDI) including an appropriate amount of additives to be added. To simplify the studies, the investigations of the PLA compounded are carried out by using differential scanning calorimeter (DSC) to clarify the glass transition, crystallization, and melting performance, using scanning electron microscope (SEM) to observe the compatibility, and using polarizing optical microscope to trace the crystallization.
