摘要：

为解决涤纶织物的易起静电问题,通过多巴胺原位聚合和氧化石墨烯循环浸渍层层自组装负载实现其抗静电功能,制备一种涤纶基抗静电织物。借助扫描电子显微镜、红外光谱仪、织物静电测试仪等表征织物的结构和抗静电性能。结果表明:多巴胺的引入有利于氧化石墨烯的负载,同时增加织物表面的亲水基团,直接改善涤纶织物的抗静电性能;当氧化石墨烯质量浓度低于20 g/L时,随着其质量浓度的增加,织物的抗静电性能逐渐提高,当质量浓度保持在15 g/L时,平纹涤纶织物的表面静电压和半衰期分别为1 156 V、1.210 s,斜纹涤纶织物的表面静电压和半衰期则为1 243 V、1.510 s;经15次水洗,平纹涤纶织物的表面静电压和半衰期仍能达到1 179 V和1.290 s,斜纹涤纶织物表面静电压和半衰期可达1 263 V和1.580 s。

Abstract:

In order to solve the electrostatic problem of polyester fabrics, the polyester fabric specimens was cyclically impregnated in graphene oxide solution after treated by in-situ polymerization of dopamine. The structure and antistatic property of the polyester fabric were characterized by scanning electron microscope, infrared spectrometer and fabric electrostatic tester. The results show that the introduction of dopamine is beneficial to the loading of graphene oxide, and the hydrophilic groups are increased to improve the antistatic performance of polyester fabric after treatment. When the graphene concentration keeps lower than 20 g/L, with the increase of graphene oxide concentration, the antistatic property of the fabric is gradually improved. When the concentration of graphene oxide is 15 g/L, the surface static voltage and half-life of the plain polyester fabric are 1 156 V and 1.210 s respectively, while that of twill polyester fabric are 1 243 V and 1.510 s. After 15 cycles of washing, the surface static voltage and half-life of the plain polyester fabric could still reach 1 179 V and 1.290 s, while that of twill can also reach 1 263 V and 1.580 s.

Key words: polyester fabric, dopamine, graphene oxide, antistatic property, antistatic finishing
