摘　　要：采用三氯化镧、肉桂酸、咪唑三元配位的稀土镧配位抗菌剂来改善低密度聚乙烯(LDPE)薄膜的抗菌性能,并且研究了抗菌剂添加量对抗菌性能、拉伸强度、断裂伸长率以及抗菌LDPE薄膜料的熔体流动速率的影响。结果表明,抗菌剂的加入可以显著提高LDPE薄膜的抗菌性能。抗菌剂添加量为2%(质量分数)时,抗菌性能最为优异,而且拉伸强度、断裂伸长率和熔体流动速率较好。The rare earth La complex antibacterial agents having LaCl3, cinnamic acid and imidazole were used to improve antibacterial property of LDPE film. The effect of content of antibacterial agents on antibacterial property, tensile strength, elongation at break and melt flow rate was studied. The results show that antibacterial agents can explicitly improve antibacterial property. When mass fraction of antibacterial agents is 2%, the optimum antibacterial property and favorable tensile strength, elongation at break and melt flow rate are obtained.
