Abstract :
Poly(lactic acid) (PLA)/Polybutylene adipate co-terephthalate (PBAT) blend and its nanocomposites were prepared using melt blending technique. Glycidyl methacrylate (GMA) has been used as a reactive compatibilizer to improve the interface between PLA and PBAT. Mechanical studies indicated an increase in impact strength and tensile modulus of PLA matrix with the increase in PBAT loading. PLA/PBAT blend prepared at ratio of 75:25 exhibited optimum impact strength. Further, incorporation of GMA to the tune of 5 wt.% and nanoclay shows an increase of impact strength. Morphological interpretations through SEM reveals improved interfacial adhesion between the PLA/PBAT blend in presence of GMA and nanoclay. XRD studies indicated an increase in d-spacing in PLA/PBAT/C20A blend nanocomposite thus revealing intercalated morphology. DSC and TGA thermograms also showed improved thermal properties as compared with virgin PLA. DMA tests revealed an increase in damping factor, confirming strong influence between PLA/PBAT blend in presence of GMA and nanoclay.
