以三嵌段共聚物（Pluronic P123和F127）为结构导向剂，将介孔二氧化锰超级电容器电极材料电化学沉积在涂有Pt的硅衬底上.用X射线衍射（XRD）、扫描电镜（SEM）和透射电镜（TEM）对二氧化锰薄膜的沉积电极进行了物理表征，并在0.5M Na2SO4电解液中用循环伏安法（CV）对二氧化锰薄膜的电化学性能进行了表征。以F127为模板的介孔MnO2在10mVs− 1的扫描速率下获得了449Fg− 1的最大比电容（SC）值。
Mesoporous manganese dioxide supercapcitor electrode materials were electrochemically deposited onto silicon substrates coated with Pt using triblock copolymer species (Pluronic P123 and F127) as the structure-directing agents. Deposited electrodes of manganese dioxide film were physically characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and were electrochemically characterized by cyclic voltammetry (CV) in 0.5M Na2SO4electrolyte. Maximum specific capacitance (SC) values of 449Fg−1was obtained at a scan rate of 10mVs−1from F127 templated mesoporous MnO2.
