Abstract

The invention discloses a preparation method of a conductive polymer film having an inverse opal structure. The preparation method comprises that an electrochemical polymerization reaction occurs based on polymeric microspheres (comprising polystyrene microspheres or amino-polystyrene microspheres) as templates, and then the conductive polymer film having an inverse opal structure is obtained by impurity removal treatment and polymeric microsphere removal treatment. The preparation method has simple processes, utilizes the polymeric microspheres as hard templates, and can be carried out at a room temperature without harsh reaction conditions. The prepared conductive polymer film having an inverse opal structure has tidy morphology and good structural environment stability.
