Novel Metal-Like Luster Conductive Film Made of Pyrrole and Furfural in Straightforward Chemical Copolymerization
Novel metal-like luster conductive films were prepared using straightforward chemical copolymerization of pyrrole (Py) and furfural (FFr). Critical parameters in the copolymerization such as monomer feed, reaction solvent, acid catalyst were studied to optimize their syntheses, film-forming properties, etc. These films showed a metal-like black luster and exhibited excellent mechanical properties with flexibility. The conjugate chemical bonds obtained from methine group were revealed in the copolymer film by Fourier transform infrared (FT-IR), ultraviolet visible light (UV-vis), and H-1 nuclear magnetic resonance (NMR) spectra. Differential scanning calorimetry (DSC) and cyclic voltammetry (CV) results implied that these copolymers showed better thermo and electrochemical stability. The density and smooth surface of the copolymer films contributed to the performance of metal-like luster, presenting the benefit of better surface reflection in the incident light.
