Title Controllable trim of graphene and synthesis of its composite with polyaniline
Abstract
Because of their excellent physical and chemical properties, graphene and polyaniline (PANI) are applied in many fields, respectively. Recent years, graphene oxide/PANI composite has attracted great interest.. Reports on graphene or graphene oxide /PANI complexes include two categories: combination by fiber-sheet or sheet-sheet modes. Those composites have excellent electrochemical properties due to the synergistic effect, which can be used as electrode materials for supercapacitors. Currently available methods of graphene/PANI composites include in-situ electrochemical anodic deposition, chemical in-situ polymerization (usually reaction system in aqueous solution), microwave radiation, etc. Anyway, researches on Graphene quantum dots/polyaniline (GQDs/PANI) composites remain little. In this thesis, Two routes were designed to fabricate GQDs/PANI composite： Firstly, GQDs and PANI nanofibers were prepared separately; and then GQDs/PANI was synthesized through ultrasonic method and further by doping-redoping process in acid or alkali solution. The other one is to prepare GQDs/PANI in-situ polymerization of aniline with the absence of GQDs.
For high performance composite electrode/probe materials, the partially reduced GQDs, which have some the carboxyl, hydroxyl and epoxy groups, were used in this article. By in-situ polymerization of aniline and mechanical mixture, GQDs was introduced into PANI to obtain GQDs/PANI complexes. The resulting GQDs/PANI composites were characterized by FT-IR, Raman, PL, UV, TEM, etc. According to the results, there are four possible effects between the GQDs and PANI: ① the electrostatic interaction, ②hydrogen bonds, ③ chemical doping, ④conjugation effect.
