碩士 === 正修科技大學 === 化工與材料工程研究所 === 101 === In this study, some kinds of monomer films were plated on the grapheme by the electrochemical polymerization , such as aniline , pyrrole , indole and 5-nitro-indole , respectively , forming a thin film for analysis. The polymer films were formed in the aqueous and organic phase solution . The properties of this polymer films were investigated by the cyclic voltammetry (CV) , Fourier transform infrared spectroscopy (FT-IR) , thermal gravimetric analyzer (TGA) , scanning electron microscopy (SEM) , differential scanning calorimetry (DSC) and charge-discharge test . SEM images showed the coralline structure of the polyaniline , granular accumulation structure of the polypyrrole and aniline-pyrrole copolymer , flaky accumulation structure of the poly 5-nitro-indole and 5-nitro-indole-indole copolymer . However , after charge and discharge the surface of the pole piece will show significantly larger cracks and variable number of phenomena , which may be due to the surface charge and discharge electrode caused by rearranging the structure . However , TGA was tested 5% thermal weight loss and electrochemical synthesis in aqueous in the lowest temperature aniline-pyrrole copolymer at a temperature of 302℃ and electrochemical synthrsis in organic phase in the lowest temperature poly-5-nitro-indole at a temperature of the 358 ℃.DSC images showed the glass transition temperature is the lowest in aqueous aniline-pyrrole copolymer and lowest organic poly-5-nitro-indole . Finally , the assembly of a flexible bettery . The charge-discharge test are poly-5-nitro-indole of the positive electrode and polyaniline of the negative electrode the discharge time long . Poly-5-nitro-indole of the positive electrode and polyaniline of the negative electrode in different do charge-discharge cycle test find that when the discharge capacity higher of the electrolyst is PC+EC+LiPF6 .
