　　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.
