摘　　要：本文提出了聚苯胺(PANI)薄膜电极上示差脉冲伏安法可逆波理论,经验证理论和实验结果相符合.A theoretical equation describing the reversible wave in differential pulse voltammetry at polyaniline thin film-coated electrodes is derived in this paper. That isΔi = abkQTPX(K,x,ΔE,b,i,δ)where a is the electron transfer coefficient, its value is 0.5- 1, b = D/ d2(D is the diffusion coefficient in film, d is the film thickness), k is the constant of experiment, QTP is the charge of polymerization, X is the function of these parameters K, v, ΔE, b, τ, δ, and is calculated numerically. The equation is verified already and experimental results are in good agreement with the theoretical.
