摘要
以三氯化锑和四氯化锡为原料采用湿化学共沉淀法制备氧化锡锑(ATO),将其包覆在大长径比TiO2纳米线上,制成复合导电粉体,再添加到聚乙烯吡咯烷酮(PVP)纺丝液中,利用微流纺丝技术制备了结构完整、粗细均匀、排列整齐的ATO@TiO2/PVP共混导电纤维,并分别对其性能和结构进行了表征,并优化了工艺条件。结果表明:以15.0%PVP乙醇溶液作为纺丝液、添加4.5%ATO@TiO2导电填料时制备的ATO@TiO2/PVP共混纤维性能较好,直径平均约为3μm,粗细均匀,互相之间基本无粘连和缠结,ATO@TiO2/PVP共混纤维最小电阻率平均为70.0 KΩ·cm。
In this paper, antimony tin oxide(ATO) was prepared by wet chemical co-precipitation using antimony trichloride and tin tetrachloride as raw materials, and it was coated on a large aspect ratio TiO2 nanowire to make a composite conductive powder. It is added to the polyvinylpyrrolidone(PVP) spinning solution, and the ATO@TiO2/PVP blended conductive fiber with complete structure, uniform thickness and neat arrangement is prepared by micro-flow spinning technology. And it also characterizes their performance and structure respectively,and optimize the process conditions. The results show that when using 15.0% PVP ethanol solution as the spinning solution and adding 4.5% ATO@TiO2 as the conductive filler, the prepared ATO@TiO2/PVP blend fiber has good performance with the average diameter of about 3 μm and uniform thickness, and there is basically no stickiness and entanglement. The minimum resistivity of ATO@TiO2/PVP blended fiber is 70.0 KΩ·cm on average.
