聚羟基脂肪酸酯/氧化石墨烯复合材料的制备及性能表征OA北大核心CSTPCD
Preparation and performance characterizations of polyhydroxyalkanoate/graphene oxide composites
采用熔融机械共混技术制备了聚羟基脂肪酸酯(PHA)/氧化石墨烯(GO)复合材料,通过拉伸性能测试、差示扫描量热分析、X射线衍射和扫描电子显微镜表征等手段,系统研究了GO对PHA基体材料力学性能、热性能、结晶行为和微观形貌的影响.结果表明,适量GO(0.04%)的引入可显著提高PHA的拉伸强度和断裂伸长率.PHA/GO复合材料的结晶度均随GO含量的增加而提高,说明GO能够促进PHA的结晶.GO在PHA基体中分散良好,与PHA基体具有良好的相容性.综…查看全部>>
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 impr…查看全部>>
