摘要: We focused on hydrolytic degradation kinetics at 310 and 343 K in phosphate buffer to compare PLA PHB kinetic profiles. Besides, we revealed the behavior for copolymer PHBV (20 % of 3-hydroxyvalerate) blend PHB-PLA (1:1). The intensity biopolymer hydrolysis is characterized by total weight lost viscosity-averaged molecular (MW) decrement. enhanced series < PLA. Characterization includes MW crystallinity evolution (X-ray diffraction) as well AFM analysis film surfaces before after aggressive medium exposition. important impact shown.
