摘要：

A simple electrospinning method was used to control the thickness of polyacrylonitrile ( PAN)/Au modified electrode. The influence of membrane thickness to modified electrode sensitivity was discussed. In our experiment, a 20-min electrospinning time and a mass ratio of 3:1 PAN/HAuCl4 are the optimum parameters to generate the high performance PAN/Au membrane modified electrode for detecting H2O2 which has a sensitivity of 145.63 mA M-1 cm(-2)) and a wide linear range of 20 mu M-20 mM.
