| 摘 要： | 将载银抗菌剂粉末添加到低密度聚乙烯树脂中,通过共混、吹塑等工艺,制备出了抗菌薄膜。 研究表明,随着载银抗菌剂含量的增加,抗张强度和伸长率的变化趋势为先增大再减小,透过率逐渐减小,摩擦系数则逐渐增大,透湿系数变化趋势为先减小再增大。 扫描电镜?毂砻?抗菌剂在基体树脂中分散均匀。 以金黄色葡萄球菌为指标的抗菌性能测试表明,载银抗菌薄膜具有较好的抗菌性。

| Abstract: | Silver-loaded antibacterial agent powder was added to low density polyethylene resin. Antibacterial film was prepared through blending and blow molding. Research showed that with increase of the antibacterial agents, the tensile strength and elongation of films first increase and decrease afterward and transparency decreases gradually; the coefficient of friction increases gradually, and permeability coefficient changes trend for first decreasing then increasing. Observation of scanning electron microscopy showed that antimicrobial agent dispersed evenly. With staphylococcus aureus as index of the antibacterial properties, test results showed that the silver-loaded antibacterial film has good antibacterial activity. |
