棉织物石墨烯涂层及其导电性能研究

摘要

采用导电性优异的石墨烯为导电填料应用在涂料中制备石墨烯功能涂料,并用于棉织物涂层.研究了石墨烯涂料的粒径、黏度及附着力,同时研究了织物导电性.实验表明:石墨烯质量分数为0.8％的石墨烯涂料在棉织物上涂覆6层时,涂层的电阻率仅为46.8Ω·cm,涂层的导电性能较好.水洗前后涂层织物的导电性变化不大,石墨烯涂层耐水洗牢度较好.%Graphene was used as a conductive material to prepare graphene functional coating for its excellent electrical conductivity, and the graphene functional coating was applied on cotton fabric. The particle size, viscosity and adhesive force of the graphene functional coating were investigated, as well as the electrical conductivity. The results showed that when cotton fabric was coated 6 times with 0.8％ graphene coating, the electrical resistivity of cotton fabric coating was only 46.8 Ω·cm, and the electrical conductivity was better. The electrical conductivity of cotton fabric coating was unchanged after washing, which meant the graphene coating presented good washing fastness.
