| 논문초록 | In this work, carboxymethyl cellulose/graphene oxide (CG) composite films with different amounts of carboxymethyl cellulose were prepared by simple mixing and evaporation method. The CG films with no electrical conductivity can be converted to reduced CG (rCG) with electrical conductivity by thermal reduction process. The CG films are flexible and retained after reduction. However, when the mass ratio of carboxymethyl cellulose and GO was 1:1, it was confirmed that the flexibility was lost after reduction. Morphologies and crystal structures of the CG and rCG films were characterized by scanning electron microscopy and X-ray diffraction. Chemical compositions of rCG films were explored by X-ray photoelectron spectroscopy. Electrochemical behaviors, such as cyclic voltammetry, galvanostatic charge/discharge, and electrochemical impedance spectroscopy, were evaluated. As a result, the areal specific capacitance of rCG films was increased as a function of carboxymethyl cellulose content. |
