An Interconnected Hierarchical Porous Carbon Material Prepared by Polymer Precursor and Its Application as Electrode in Supercapacitors

摘要

Interconnected hierarchical porous carbon (IHPC) was prepared by a Poly(high internal phase emulsion) (polyHIPE) and carbonation method based on phenolic-formaldehyde resin for supercapacitors. Structural and morphological characterizations of IHPC were carried out using field emission scanning electron microscopy (SEM). Capacitive behaviors of IHPC were investigated by cyclic voltammetry and galvanostatic charge-discharge. Electrochemical tests showed IHPC material have a maximum capacitance of 106 F/g and good cycle stability for supercapacitor application.
