摘　　要：为进一步提高石墨烯基纳米复合材料的远红外发射特性,通过一步水热法利用锆钛氧化物对氧化石墨烯进行纳米复合改性,制备了二氧化锆/二氧化钛/还原型氧化石墨烯(ZrO 2/TiO 2-rGO)纳米复合材料。以水溶性聚氨酯为黏合助剂将ZrO 2/TiO 2-rGO与纺织品相结合,制备出具有远红外发射性能的棉织物。借助扫描电子显微镜和傅里叶红外分析光谱对制备的ZrO 2/TiO 2-rGO复合材料表观形态和内部结构进行表征;通过远红外发射率和红外热成像技术表征了改性棉织物的远红外发射性能。结果表明:在温度为120℃,时间为4 h,氧化石墨烯、二氧化钛、氧氯化锆质量比为5∶3∶2的合成条件下整理棉织物时,其远红外发射率较未整理棉织物高出约2.5%;这种方法可有效减少石墨烯含量,且远红外发射性能优良。In order to further improve the far-infrared emission characteristics of graphene-based nanocomposites,zirconia/titania/reduced graphene oxide(ZrO 2/TiO 2-rGO)nanocomposites were prepared by one-step hydrothermal modification of graphene oxide with zirconia/titanium oxide.Cotton fabrics with far-infrared emissivity were prepared by combining ZrO 2/TiO 2-rGO with the textiles using water-soluble polyurethane as binder.The morphology and internal structure of ZrO 2/TiO 2-rGO composites were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy,and the far infrared emission properties of modified cotton fabrics were characterized by far infrared emissivity and infrared thermal imaging technology.The results show that at 120℃for 4 reaction hours,the far-infrared emissivity of the treated cotton fabric was about 2.5%higher than that of the untreated cotton fabric when the mass ratio of graphene oxide,titanium dioxide,zirconium oxychloride was 5∶3∶2.This method could effectively reduce the content of graphene and provide good far-infrared emission performance with low cost.
