聚羟基脂肪酸酯/氧化石墨烯复合材料的制备及性能表征
Preparation and performance characterizations of polyhydroxyalkanoate/graphene oxide composites
摘要
Abstract
In this study,poly(hydroxyalkanoate)(PHA)/graphene oxide(GO)composites were prepared through melt blending,and the effect of GO on the mechanical properties,thermal properties,crystallization behavior,and microstruc-ture of the composites was systematically investigated by tensile testing,differential scanning calorimetry,X-ray diffrac-tion,and scanning electron microscopy.The results indicated that introducing an appropriate amount of GO(0.04 wt%)could improve the tensile strength and elongation at break of PHA significantly.The crystallinity of the PHA/GO com-posites increased with an increase in the GO content,indicating that GO could promote the crystallization of PHA.SEM observation demonstrated that GO was well dispersed in the PHA matrix and exhibited good compatibility with PHA.In summary,GO can act as an ideal modifier to reinforce and toughen PHA.关键词
