摘　　要：以镀银纱线为基底材料,采用恒电位法在0.9%的NaCl溶液中制备了4种不同沉积电压(0.50、0.60、0.70、0.80 V)Ag/AgCl纱线参比电极。研究了Ag/AgCl纱线参比电极电化学阻抗、电位稳定性、温度影响、酸碱度影响、可逆性和再现性。结果表明,随着沉积电压的升高,镀银纱线表面生成的氯化银颗粒粒径增大且分布面积增大,其中0.60 V沉积电压制备的Ag/AgCl纱线参比电极,氯化银颗粒均匀分布,纱线表面为极化-非极化复合结构,电化学阻抗最低、电位稳定性最好、温度及酸碱环境的变化对电极电位影响小、可逆性好且具有良好的电位重现性。Ag/AgCl yarn reference electrodes with different deposition voltages(0.50,0.60,0.70,0.80 V)were prepared by constant potential method in 0.9%Nacl solution with silver-plated yarn as base material.The electrochemical impedance,potential stability,temperature effect,pH effect,reversibility and reproducibility of Ag/AgCl yarn reference electrode were investigated.The results show that with the increase of deposition voltage,the particle size and distribution area of silver chloride particles on the surface of silver-plated yarn increased.The Ag/AgCl yarn reference electrode prepared by deposition voltage of 0.6 V had uniform distribution of silver chloride particles,and the yarn surface had a polarization and non-polarization composite structure.The electrochemical impedance is the lowest,the potential stability is the best,the change of temperature and acid-base environment has lttle influence on the electrode potential,the reversible and the potential reproducibility is good.
