以涤/棉(T/C)混纺织物为基材,石墨烯(Gr)、氧化石墨烯(GO)和还原氧化石墨烯(RGO)为导电填料,采用多次浸渍-烘干工艺分别制备了石墨烯-涤/棉复合织物(T/C-Gr)、氧化石墨烯-涤/棉复合织物(T/C-GO)及还原氧化石墨烯-涤/棉复合织物(T/C-RGO)。通过热重分析、傅里叶变换红外光谱、扫描电子显微镜和电阻测量等手段,对复合织物的热稳定性、化学结构、微观形貌及导电性能进行了分析与对比。结果表明,石墨烯类材料可通过物理吸附和化学还原负载在织物表面,赋予织物导电性能。其中,GO在T/C-GO上分布均匀,但不具有导电性;T/C-Gr和T/C-RGO则表现出一定的导电性,并且RGO在T/C-RGO表面分布更均匀,导电性能和摩擦牢度均优于T/C-Gr,展现出更优的综合性能和实际应用潜力。
Polyester/cotton blended fabric (T/C) was used as the substrate,and graphene (Gr),graphene oxide (GO) and reduced graphene oxide (RGO) were employed as conductive fillers to prepare graphene-polyester/cotton fabric (T/C-Gr),graphene oxide-polyester/cotton fabric (T/C-GO) and reduced graphene oxide-polyester/cotton fabric (T/C-RGO) by multiple dipping-drying method.The thermal stability,chemical structure,surface morphology and electrical conductivity of the composite fabrics were characterized using thermogravimetric analysis (TGA),Fourier-transform infrared spectroscopy (FT-IR),scanning electron microscopy (SEM) and resistance measurements.The results showed that graphene-based materials could be effectively loaded onto the fabric surface through physical adsorption and chemical reduction to impart electrical conductivity to the fabrics.Among them,GO was uniformly distributed on T/C-GO but lacked conductivity.In contrast,both T/C-Gr and T/C-RGO demonstrated electrical conductivity performance.Moreover,RGO was more evenly distributed on the surface of T/C-RGO,and its electrical conductivity and friction fastness were superior to those of T/C-Gr,demonstrating superior comprehensive performance and practical application potential.
