Abstract
Stereocomplexation is utilized to improve and control the mechanical and thermal properties of poly(lactic acid) (PLA) where enantiomeric polymers poly(l-lactic acid) (PLLA) and poly(d-lactic acid) (PDLA) form stereocomplexation. This research reports the effects of minor amounts of PDLA on the properties of PLLA/microcryslalline cellulose (MCC)/PDLA blends. Blends of PLLA/MCC/PDLA are prepared with constant percentage of MCC and different percentage of PLLA and PDLA by solution casting methods and are characterized by FTIR for the confirmation of blends compatibility, WAXS and SEM for the analysis of morphology, TGA and DTA for thermal properties measurement. Shifting of peaks of FTIR profiles observe in blends with and without PDLA due to hydrogen bonding which helps to have compatibility of blends component. XRD analysis…
