摘要:
采用乙烯基硅烷在氢氧化镁晶须(MH)表面引入乙烯基后与不同单体进行原位聚合，制备了改性氢氧化镁晶须(MMH),通过熔融复合与注射成型的方法制备了聚丙烯/晶须（PP/MH）复合材料，并对复合材料的结构与性能进行了表征.结果表明：原位聚合改性增强了MH与PP之间的界面相互作用力，提高了PP/MH复合材料的冲击强度；填充甲基丙烯酸甲酯（MMA）/丙烯酸丁酯（BA）共单体原位聚合改性MH与MMA原位聚合改性MH相比，PP/MMH复合材料的拉伸强度和冲击强度均有显著提高.
Abstract:
The magnesium hydroxide (MH) whiskers were modified by in situ polymerization of diverse monomer in the presence of surfacefunctionalized MH,which were previously modified by 3(trimethoxysilyl) propyl methacrylate,and then compounded with PP in molten state. The effects of MH whisker grafted with polymer on the properties of PP/MH composites were studied by SEM,DMA and tensile testing machine. Compared with the PP/MH composites filled with untreated MH whisker,the notched impact energy of PP/MMH composites containing modified MH whisker were found to be significantly improved,especially for MMA/BA comonomer modified MH whisker.
