- Abstract
Poly (lactic acid) (PLA) /reed fiber (RF) blends with different contents of RF were prepared through melt blending, and the corresponding films were prepared by blow molding. The biodegradability properties of PLA/RF blending films were investigated in the presence of proteinase K, and their crystallization behavior and surface morphological evolution during the degradation of the samples were also determined by using differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) . The results indicated that the enzymatic degradation of PLA was promoted by RF, and the enzymatic degradation rate of PLA/RF composites increased with an increase in the RF content. The degradation rate of composite films containing 30 wt% RF was the fastest, resulting in 81. 11% degradation in 16 days. The addition of RF could reduce the crystallinity of PLA, affecting the degradation rate.
