石墨烯发泡涂层织物的制备及其性能

Preparation and properties of graphene foam coated fabric

为开发可应用于电焊防护服的织物,针对防护性和穿着性差的问题,采用发泡涂层的方式将石墨烯涂覆到织物上并使用黏合剂进行整理。对织物的形貌特征进行了分析,并对织物的透气性、抗金属熔滴冲击与红外光吸收等性能进行了测试。结果表明:石墨烯发泡涂层织物表面的石墨烯成膜尺寸随质量分数增加而增大,经黏合剂处理后的织物石墨烯质量分数越高,抗金属熔滴冲击性越好,红外吸收升温降低,同时对透气性影响较小。石墨烯质量分数为2%时,熔融金属冲击升温为23℃,比对照组下降7℃;红外升温稳定在22.5℃,比对照组下降0.7℃;透气性为32.72 mm/s,未经黏合剂处理的织物是16.97 mm/s。黏合剂处理后的石墨烯发泡涂层织物可用于制作电焊防护服。

In order to develop the fabric which can be used in welding protective clothing,graphene was coated on the fabric by foaming coating method to improve the protection and comfort.The air permeability,molten metal splashes and IR absorption of the fabric after coating were tested,and its morphology characteristics were analyzed.The results show that the graphene film size on the surface of the coated fabric increased with concentration.The higher the concentration of fabric graphene treated with adhesive,the better resistance to metal droplets splashes,the lower the infrared absorption temperature,and the less the influence on air permeability.When the graphene concentration is 2%,the metal droplet temperature rises to 23℃which declines 7℃than control group.Infrared heating is stable at 22.5℃,which is lower than the control group.The air permeability is 32.72 mm/s,while the graphene coated fabric without adhesive treatment was 16.97 mm/s.In conclusion,the graphene foam-coated fabric after adhesive treatment can be applied to welding protective clothing fabric.
