Synthesis Optimization of Polyaniline and its Electrochemical Performance

摘要: 运用正交试验法研究了温度、酸浓度、氧化剂配比、金属离子掺杂对乳液聚合聚苯胺性能的影响, 结果表明, 反应最佳条件为NH₄S₂O₈ (m=1.5g):An=3:5、HCl浓度1.2mol/L、反应温度20℃、掺杂离子为Fe³⁺。不同条件下合成的掺杂态聚苯胺经红外、电导率测定以及循环性能测试, 证明, 掺杂聚苯胺具有较好的电化学性能。

Abstract: Orthogonal experiments were used to investigate impact of experimental conditions such as temperature, media concentration, oxidant ratio, metal ions doping on the performance of polyaniline.Optimum reaction conditions were obtained which is acid concentration of HCl 1.2mol/L, monomer ratio of NH₄S₂O₈ (m=1.5g) and An 3/5, temperature 20℃ with Fe³⁺ Doping.The doped polyaniline were characterized with FTIR and electrical conductivity under different conditions.On the basis of optimum condition, the cycle performance of polyaniline was studied.The results prove that the doped polyaniline has good electrochemical performance.
