静电纺丝法制备聚苯胺/醋酸纤维素膜修饰电极
Preparation of PANI/CA film modified electrode by electro-spinning and its application in biosensor
摘要
Abstract
Polyaniline and cellulose acetate were used as materials, and formulated into a solution at a certain ratio, and electrostatic spinning was used to prepare polyaniline/cellulose acetate (PANI/CA) nano-fiber membrane which was modified on the surface of Pt electrode to prepare the PANI/CA/Pt. PANI/CA nano-fiber film was characterized by electrochemical methods and scanning electron microscopy(SEM). The results indicate that electrochemical properties of PANI/CA nano-fiber film are stable, and SEM images show their meshy irregular stereoscopic distribution on electrode surface. The electrode modified with nano-fiber film shows polyaniline characteristic peaks in H2SO4 solution and its dynamic process on the electrode surface is investigated with AC impedance. The prepared GOx/PANI/ CA/Pt modified electrode has a good response to glucose, which is expected to be a good and inexpensive biosensor. It is a truly original and feasible method to use the nanofibers film modified electrodes prepared by the Electrostatic Spinning method to immobilize polymer substances such as enzyme and protein.关键词
