Preparation and Characterization of Pyrrole-(3,4-ethylenedioxythiophene) Copolymer Ordered Nanoarray Film†

We adopted the anodic aluminum oxide(AAO) template electrochemical deposition method for synthesis of a new type of copolymer nano array membrane structure as lithium ion battery electrode material. This pyrrole-(3,4-ethylenedioxythiophene)(PE) copolymer nano-array membrane material has a lot of advantages, such as better electrochemical properties. The specific capacity can reach 1426.1 mA·h/g(the charge and discharge current density is 100 mA/g) and good cyclic stability(after 300 cycles of charging and discharging, the specific capacity remains above 1400 mA·h/g). Therefore, this multi-component polymer nanowire array may be widely developed for the next generation of long life, high-performance lithium-ion battery electrode materials.
