采用水热法合成石墨烯气凝胶,将其研磨成粉末与低表面能物质聚二甲基硅氧烷混合喷涂在棉织物表面,制备了石墨烯基超疏水导电纺织品。采用红外光谱仪(FT-IR)、X射线能谱仪(XPS)、扫描电子显微镜(SEM)等手段对石墨烯气凝胶和超疏水导电纺织品进行了测试表征。研究不同含量聚二甲基硅氧烷对整理棉织物水接触角和电阻率的影响。结果表明:水热反应制备的石墨烯气凝胶具有良好的三维网络粗糙结构,利于构建超疏水表面所需的微观粗糙度,同时由于其特有的导电性能,为超疏水导电材料制备提供了有利条件。当聚二甲基硅氧烷浓度为5%时,整理棉织物兼具优异的超疏水性能和导电性能,水接触角高达160.4°,且电阻率仅为340Ω/cm,具备良好的导电性,同时实现了优异的抗污、防水性能。
The graphene(rGO) aerogel was prepared by the hydrothermal method.The rGO-based superhydrophobic conductive textile was prepared by spraying the mixture of the aerogel powder and polydimethylsiloxane.The rGO aerogels and superhydrophobic conductive textiles were characterized by infrared spectroscopy (FT-IR),X-ray energy spectrometer (XPS) and scanning electron microscope (SEM).The effect of different content of polydimethylsiloxane on the water contact angle and resistivity of finished cotton fabrics was studied.The results shown that the rGO aerogel prepared by the hydrothermal reaction exhibited good 3D network rough structure,which was conducive to the construction of the micro-roughness required for the superhydrophobic surface.Moreover,due to its unique conductivity,it provided requirement for the preparation of superhydrophobic conductive materials.With 5% polydimethylsiloxane,the finished cotton fabric exhibited high water contact angle of 160.4°,and good resistance of 340Ω/cm.The finished cotton fabric exhibited good conductivity,excellent anti-fouling and waterproof properties.
