摘　　要：采用醇盐水解沉淀法制备出粒度为40nm、颗粒均匀的球型SiO2-W-SYJ。采用熔融共混法在线型低密度聚乙烯(LLDPE)/低密度聚乙烯(LDPE)复合体系中添加纳米SiO2-W-SYJ制成SiO2-W-SYJ/LLDPE/LDPE复合薄膜。采用TEM电镜、万能力学实验机、MIC法,研究了复合薄膜的力学性能、光学性能和抗菌性能。结果表明:该薄膜除了具有良好的力学和光学性能,突出表现出优异的抗菌性能。SiO2-W-SYJ nano-particles with mean diameters of 40 nm were prepared by means of alkoxlde hydrolysis precipitation method. A kind of functional composite membrane SiO2-W-SYJ/LLDPE/LDPE was prepared via the addition of nano-SiO2-W-SYJ particles into the composite system of LLDPE/LDPE by means of melt blending. The mechanical, optical and antimicrobial properties of the prepared membrane were characterized by means of TEM, POWER TESTING and MIC. The results indicated the membrane had good long-time bactericidal activity expect good mechanical and optical properties.
