摘要
在室温条件下的酸性溶液中,以铜片为电极,采用液体的苯胺单体作为反应剂,通过扫描伏安法制备聚苯胺薄膜.利用循环伏安法(cyclic-voltametry,C-V)、扫描电子显微镜(scanning electron microscope,SEM)、X-射线衍射测试(X-ray diffraction,XRD)等手段对样品进行表征,同时详细考察合成条件对材料性能的影响.结果表明,在苯胺浓度为0.1 mol/L,硫酸浓度为1.0 mol/L,盐酸浓度为0.5 mol/L的混合溶液中,当扫描速度为0.06 V/s时,可获得颗粒尺寸在100 nm以下且均匀度比较高的聚合物.该聚合物具有良好的氧化还原可逆性.
Polyaniline films have been synthesized on copper surface in inorganic acid aniline solution under different conditions such as scan rates and acid concentration.The properties of the polymer films were characterized by X-ray diffraction（XRD） and scanning electron microscope（SEM）.Electrochemical parameters of the films were characterized by cyclic-voltametry（C-V） lines.The results indicate that polyaniline films synthesized in 0.1 mol/L aniline containing 1.0 mol/L sulfuric acid and 0.5 mol/L hydrochloric acid solution,at the ambient temperature and scan rate 0.06 V/s have uniform grain size under 100 nm and exhibit good reversibility.
