A novel non-enzymatic sensor for the detection of hydrogen peroxide(H2O2) was prepared.It is based on a polyimide(PI) and Ag nanoparticle composite modified glassy carbon electrode.The structure and morphology of the modified electrode surface were characterized by scanning electron microscopy and atomic force microscopy.The electrochemical performance of the sensor was evaluated by cyclic voltammetry and amperometry.The results showed that under optimum conditions,the calibration plot were linear in the range of 0.01～28.88mM,with a detection limit of 0.04mM when the S/N was 3.The electrode exhibited high stability,great sensitivity,stable reproducibility and fast response time (less than 4s).It shown that PI can be used as a performance reliable and long-life sensor for H2O2 detection,exhibiting a new application for PI.
