 Polyaniline-capped mesoporous carbon nanosheets were developed using a vapor deposition polymerization process. This process allowed for the creation of highly conductive and porous materials which can be used for energy storage applications such as supercapacitors. The material was found to have excellent electrochemical properties, including a high capacitance and rate capability. These properties make it ideal for use in energy storage devices such as supercapacitors. This article was authored by Junchul No, Sukjiko, and Changmin Yoon.
