| 中文摘要 | poly(l-lactide) (pla)/silica (sio2) nanocomposites containing 1, 3, 5, 7, and 10 wt % sio2 nanoparticles were prepared by melt compounding in a haake mixer. the phase morphology, thermomechanical properties, and optical transparency were investigated and compared to those of neat pla. scanning electron microscopy results show that the sio2 nanoparticles were uniformly distributed in the pla matrix for filler contents below 5 wt %, whereas some aggregates were detected with further increasing filler concentration. differential scanning calorimetry analysis revealed that the addition of sio2 nanoparticles not only remarkably accelerated the crystallization speed but also largely improved the crystallinity of pla. an initial increase followed by a decrease with higher filler loadings for the storage modulus and glass-transition temperature were observed according to dynamic mechanical analysis results. hydrogen bonding interaction involving c=o of pla with si-oh of sio2 was evidenced by fourier transform infrared analysis for the first time. |
