The demand for textiles equipped with multiple functionalities is high. This work aimed to develop ultralight versatile protective polyurethane/graphene fabrics with excellent water‐protective, antistatic, UV protection and crocking performance using pad knife coating technology. The prepared fabrics were characterized using scanning electron microscopy and Fourier transform infrared and Raman spectroscopies. The effects of graphene and toluene concentrations on the morphological, water‐protective, electrical, UV protection and crocking properties were evaluated. Results showed that fabrics coated with 3 wt% graphene had better antistatic property (298.3 kV/1.23 s), good water repellency (80%), outstanding water resistance (153 kPa), relatively high water contact angle (103.2°) and modest crocking and mechanical performance (grade 3, 15.06/11.86 N). Furthermore, UV protection abilities increased from 35.71 to 2000, up to fivefold higher than those of previously reported graphene‐based coated fabrics. As a polar solvent, toluene exerted a positive effect on the promotion of molar polarization, improving the antistatic property. The facile coating technology is simple, can be used in versatile protective applications and is suitable for large‐scale production. © 2020 Society of Industrial Chemistry

聚氨酯/石墨烯涂料的量产以及对超轻尼龙织物的耐久性和多功能保护的影响

对具有多种功能的纺织品的需求很高。这项工作旨在使用垫刀涂布技术开发具有优异的防水，防静电，防紫外线和抗磨性能的超轻型多功能聚氨酯/石墨防护织物。使用扫描电子显微镜和傅立叶变换红外和拉曼光谱对所制备的织物进行表征。评估了石墨烯和甲苯浓度对形态，保水，电，紫外线防护和耐摩擦性能的影响。结果表明，涂​​覆有3 wt％石墨烯的织物具有更好的抗静电性能（298.3 kV / 1.23 s），良好的拒水性（80％），出色的耐水性（153 kPa），相对较高的水接触角（103.2°）和适度的摩擦和机械性能（等级3，15.06 / 11。86 N）。此外，紫外线防护能力从35.71增加到2000，比以前报道的石墨烯基涂层织物高五倍。甲苯作为极性溶剂，对促进摩尔极化起积极作用，提高了抗静电性能。简便的涂层技术非常简单，可用于多种保护性应用，并且适合大规模生产。©2020工业化学学会 可用于多种防护应用，适合大规模生产。©2020工业化学学会 可用于多种防护应用，适合大规模生产。©2020工业化学学会
