摘　　要：通过简单的丝网印花工艺,将磷酸(PA)、石墨烯(Graphene)及微晶纤维素(MCC)混合物涂覆在棉织物上,制备具有光热转换效果的石墨烯涂层棉织物。光学显微镜观察发现石墨烯在磷酸与微晶纤维素中具有优异的分散性,扫描电子显微镜观察到导电棉织物上石墨烯-微晶纤维素涂层的生成。采用0.6%石墨烯分散液两次涂覆工艺制备的复合织物,在一个太阳光强度下迅速升温至65℃,具备良好的光热转换性能。为使复合织物可以适应复杂的应用环境,在复合织物上覆盖有机硅弹性体薄膜,使其接触角达到105.75°,表现出良好的疏水效果。A graphene-coated cotton fabric with photothermal conversion effect is fabricated by coating a mixture of phosphoric acid(PA),graphene,and microcrystalline cellulose(MCC)onto the cotton fabric with screen printing process.Optical microscopy reveals excellent dispersion of graphene in phosphoric acid and microcrystalline cellulose,while scanning electron microscopy(SEM)confirms the formation of a graphene-microcrystalline cellulose coating on the conductive cotton fabric.The composite fabric rapidly heats up to 65℃under one sunlight intensity when coating 0.6%graphene twice,demonstrating superior photothermal conversion performance.The composite fabric is coated with a silicone elastomer film to enhance its adaptability to complex application environments,resulting in an increased contact angle of 105.75°and improved hydrophobic properties.
