摘　　要：为研究聚苯胺/蚕丝复合织物对酸碱的颜色响应性和可逆重复性,以平纹蚕丝织物作为基底,过硫酸铵为氧化剂,十二烷基苯磺酸为掺杂剂,通过原位化学氧化法制备了聚苯胺/蚕丝复合导电织物,采用测色仪测定织物表面颜色、色彩坐标,积分球测定织物的紫外光可见光反射曲线,研究了聚苯胺/蚕丝织物对p H值的响应性。结果表明:该复合织物的表面颜色随p H值从1增加至12发生由墨绿色—蓝绿色—蓝黑色之间的变化,具有良好的p H值响应性;此外,聚苯胺/蚕丝织物可在不同p H值溶液中重复可逆使用,表面色差小于2,颜色差异轻微,具有稳定的开关效应。In order to investigate color response and reversibility of polyaniline-coated silk fabric to p H value,polyaniline-coated silk fabric was prepared by an in-situ chemical polymerization in the presence of ammonium persulfate as the oxidant and dodecyl benzene sulfonic acid as the dopant. The color and color coordinates of polyaniline（ PANI）/silk composite fabrics were measured by the colorimeter. UVVis reflectance spectra of fabrics were determined by the integrating sphere. The effect of p H value on the color of PANI/silk was investigated. It is found that the color of composite textile shows p Hresponsive function,its color can change from dark green to blue green,and dark blue when the p H increase from 1 to 12. In addition,PANI/silk can be reused reversibly in different p H solutions and has a stable switching effect.
