聚烯烃/纳米SiO2复合材料研究进展

论述了纳米SiO2的表面处理方法、复合材料的制备技术及其力学和光学性能。表明纳米SiO2分散于聚烯烃(PP、HDPE)中,可以提高基体的韧性、强度和模量。以纳米SiO2作为填料的聚乙烯棚膜,呈现优良的红外线吸收性能和可见光透过性能。为此,纳米SiO2可作为一种聚乙烯农膜的新型保温剂。     

Water bamboo husk reinforced poly(lactic acid) green composites

The water bamboo husk is one of major agricultural wastes in Taiwan. In this study, the powder obtained from the water bamboo husk was added to poly(lactic acid) (PLA) to form novel reinforced biodegradable composites. Morphologies, mechanical properties, and heat resistance of these water bamboo powder reinforced composites were investigated. The results indicate that the char yields were increased as plant powder was incorporated to PLA. In addition, the mechanical properties were also enhanced due to the addition of powders. The increments of storage moduli of PLA were about 50–200%. Moreover, the increments of loss moduli of PLA were about 70–200%. On the other hand, the T_g of PLA was slightly decreased by the addition of powder, and this may improve the brittle characteristics of PLA. Furthermore, this type of reinforced PLA would be more environmental friendly than the artificial additive‐reinforced one. POLYM. ENG. SCI., 2008. © 2008 Society of Plastics Engineers
