| 英文摘要 | Polylactic acid (PLA)/pearlescent pigments (PEPs) composites were fabricated by melt blending method and their properties were studied using a rotational rheometry, field emission scanning electron microscopy (FESEM), differential scanning calorimetry (DSC) and X-ray diffractometry (XRD). Because PEP could disperse uniformly in PLA matrix and would form PEP networks, there were improvements made in the flexural strength, tensile strength and impact strength of PLA composites. Interestingly, the viscosity of PLA composites reduced significantly as compared with neat PLA, indicating an improvement in processing properties. The rheological tests confirmed that the storage modulus of PLA composites decreased as PEP content increased at a given frequency. Also, there was a plateau at low frequency range, which was a sign of PEP networks formation. The DMA tests showed that the storage modulus of PLA composite increased with PEP content, suggesting the enhancement of rigidity. According to the XRD results, no change was observed in the crystal structure of PLA in the presence of PEP. The addition of PEP did not change melting temperature, but the glass transition temperature increased a little, and the cold crystallization temperature of PLA decreased largely. The DSC results also showed that nucleation ability of PLA was enhanced by addition of PEP at low cooling rates, but the whole crystallization process of PLA in composite was inhibited at higher cooling rates. This conclusion was also confirmed by the results of crystallization kinetics. |
