摘　　要：为获得具有良好力学性能的胶原蛋白基复合材料,以聚乙烯(PE)和胶原蛋白为原料,以过氧化二异丙苯为引发剂,分别采用乙烯与丙烯酸的共聚物(EAA)和聚乙烯接枝马来酸(PE-g-MAH)为增容剂制备聚乙烯/胶原蛋白复合材料。过程中分别考察了制备工艺、增容剂的用量、胶原蛋白的用量对复合材料的影响。研究结果表明:(1)采用反应增容双螺杆连续挤出的工艺较优;(2)确定了PE/胶原蛋白/PE-g-MAH的重量比100:15:15时,复合材料的综合力学性能最优,断裂伸长率、拉伸强度和冲击强度分别为88.6%、12.5 MPa、26.7 kJ·m-2;(3)确定了PE/胶原蛋白/EAA的重量比100:15:20时,复合材料的综合力学性能最优,断裂伸长率、拉伸强度和冲击强度分别为90.5%、11.8 MPa、21.5 kJ·m-2。The polyethylene/collagen based composites with good mechanical properties were prepared by using dicumyl peroxide as initiator, ethylene acrylic acid copolymer （EAA） and polyethylene-graft-maleic anhydride （PE-g-MAH） as compatibilizer, respectively. The influence of preparation process, the amount of compatibilizer, and the amount of collagen on the composite properties were studied in details. The results show that： （1） The process of reactive compatibilization by using twin screw extrusion is better than others; （2） The polyethylene/collagen composites reach the optimal mechanical properties when the PE-g-MAH was used as compatibilizer and the weight ratio of PE/collagen/PE-g-MAH is 100：15：15, the elongation, tensile strength and impact strength are 88.6%, 12.5 MPa and 26.7 kJ.m-2, respectively; （3） The polyethylene/collagen composites reach the optimal mechanical properties when the EAA was used as compatibilizer and the weight ratio of PE/collagen/EAA is 100：15：20, the elongation, tensile strength and impact strength are 90.5%, 11.8 MPa and 21.5 kJ.m-2, respectively.
