摘　　要：用熔融挤出的方法制备了乙烯基硅烷(VS)接枝聚丙烯(PP-g-VS),用接枝改性后的聚丙烯(PP-g-VS)作为基体,与黄麻纤维经过挤出注射成型制备了聚丙烯/黄麻纤维复合材料(PP-g-VS/F)。利用红外光谱仪对接枝物进行了表征,并对复合材料的力学性能、吸水性和耐热性进行了测试,最后采用扫描电子显微镜(SEM)对复合材料的拉伸断面进行了观察。结果表明,VS成功地接枝到了PP上;经改性后的复合材料的力学性能、耐水性和耐热性都得到提高;改性后的PP-g-VS与黄麻纤维之间的界面相容性得到了明显改善。Vinyl silane （VS） grafted polypropylene （PP-g-VS） was prepared by melt extrusion technique. PP-g-VS/F composites were prepared by using modified PP-g-VS as matrix and jute fiber as reinforcing material through extrusion injection molding processing. PP-g-VS were characterized by FT-IR. The mechanical properties, water resistance and heat resistance of the composites were studied. Tensile fracture surface of the composites were observed by SEM. The results showed that： VS was successfully grafted onto PP; the mechanical properties, water resistance and heat resistance of the modified PP/jute fiber composites were all improved; the interface compatibility between modified PP-g-VS and jute fiber was improved.
