【摘要】 采用低温氧等离子体处理聚对苯二甲酸乙二酯(PET)非织造布接枝丙烯酸(AA)后,再接枝壳聚糖,探讨了氧等离子体参数对接枝AA后PET亲水性的影响,以及接枝壳聚糖后其PET非织造布抗菌性能的变化。结果表明:低温氧等离子体处理PET非织造布后,其纤维表面粗糙度增加,接枝AA后PET亲水性提高。低温氧等离子体处理PET非织造布接枝AA改性的最佳条件为:工作压强30 Pa,放电功率40 W,处理时间2 min。接枝壳聚糖后,PET非织造布具有抑菌性能,对大肠杆菌和金黄色葡萄球菌有明显的抑菌效果。更多还原

【Abstract】 Polyethylene terephthalate(PET) non-woven fabric was grafted with acrylic acid(AA) and subsequently with chitosan by low-temperature oxygen plasma.The effects of oxygen plasma parameter on the hydrophilicity of AA-grafted PET were discussed.The change in the antibacterial behavior of PET non-woven fabric after grafting with chitosan was also discussed.The results showed that the PET non-woven fabric had the surface roughness greatly increased after low-temperature oxygen plasma treatment,and the hydrophilicity of PET was improved after grafting with AA.The low-temperature oxygen plasma grafting modification conditions for PET non-woven fabric were optimized as followed: working pressure 30 Pa,discharge power 40 W,treating time 2 min.The PET non-woven fabric had the profound antibacterial effect against escherichia coli and staphylococcus aureus after grafting with chitosan.更多还原
