等离子体处理对石墨烯/涤纶复合织物结合牢度的影响研究

Research on bonding fastness of RGO/PET fabrics treated by plasma

利用常温常压等离子体对涤纶织物表面进行改性处理，使其表面引入含氮基团，然后将石墨烯通过接枝和浸渍的方式引入到涤纶织物表面，制备成石墨烯／涤纶复合织物。通过试验对比，研究了常温常压等离子体处理后织物表面含氮基团的时效性及石墨烯／涤纶复合织物的结合牢度。等离子体即时处理与处理后放置24h后织物的氮元素比例由3．73％下降为1．33％，处理24h后制备的复合织物表面电阻率由0．124MΩ／cm2增加到O．259MΩ／cm2，说明等离子体处理具有明显的时效性；经等离子体处理复合织物水洗后表面电阻率变化率由99．1％减小到49．2％．说明等离子体处理后的涤纶织物制备的石墨烯／涤纶复合织物结合牢度显著提高。

Nitrogen-containing groups are introduced into polyester fabric by modification with normal temperature and pressure plasma, and then graphene is introduced into the polyester fabric surface by grafting and impregnation to prepare RGO/PET composite fabric. By experiment and comparison, the time effect on the nitrogen-containing groups on the surface of the fabric after normal temperature and pressure plasma treatment is researched, and also the bonding fastness of the RGO/PET composite fabric is researched. After treating with plasma for 24 h, the proportion of nitrogen in the fabric decreases from 3.73% to 1.33%, and the surface resistivity of composite fabric changes from 0. 124 MΩ/cm2 to 0.259 MΩ/cm2 after 24 h treatment. The experimental results show that the plasma treatment had obvious time effect on this composite fabric. After plasma treatment, the change rate of surface resistance of the composite fabric reduces from 99.1% to 49.2%. The experimental results show that the bonding fastness of RGO/PET composite fabric prepared by plasma-treated polyester fabric is significantly improved.
