摘要

以不同粒径的锐钛矿型TiO₂为原料,通过熔盐法制备形貌优良、长径比可控的钛基晶须,并在该晶须基础上通过液相沉积法在其表面包覆一层掺杂氯化锑的氯化锡薄膜(ATO),结合高温煅烧获得浅色导电晶须。以此浅色导电晶须为填料,对聚酯纤维织物进行表面涂层处理以提升该织物的抗静电性能。分别通过扫描电镜、傅里叶红外光谱、织物表面静电半衰期对涂层的微观形貌与结构、抗静电性能进行测试表征。结果表明:原料混合比(TiO₂∶Na₂CO₃∶NaCl)为4∶8∶1、原料TiO₂粒径为100nm制备的导电晶须性能较好;涂料中导电晶须含量为4.76%时,涂层织物的静电半衰期为1.24s,达到了国家标准GB/T 12703—2008中规定的A级标准。

Abstract

Using anatase TiO₂ with different particle sizes as raw materials,titanium-based whiskers with excellent morphology and controllable aspect ratio were prepared by molten salt method.On the basis of the whiskers,a thin film of antimony chloride-doped tin chloride (ATO) was coated on the surface by liquid deposition method,and light-colored conductive whiskers were obtained by high-temperature calcination.The light-colored conductive whisker was used as filler to coat the surface of polyester fiber fabric to improve the antistatic properties of the fabric.The microstructure,structure and antistatic properties of the coating were characterized by scanning electron microscopy,Fourier infrared spectroscopy and electrostatic half-life of fabric surface.The results showed that when the mixing ratio of raw material (TiO₂∶Na₂CO₃∶NaCl) was 4∶8∶1 and the particle size of raw material TiO₂ was 100nm,the prepared conductive whisker possessed good performance.When the mass fraction of the conductive whisker in the coating was 4.76%,the electrostatic half-life of the coated fabric was 1.24s,which reached the class A standard specified in the national standard GB/T 12703—2008.
