Study on the Structure of the Coal/ Polyaniline Composites

摘要

1. The polymerization mechanism in the aniline/coal system is similar with that of pure aniline. Coal takes as macromolecular acid promoting the aniline polymerization and doping the composite. 2. Coal-based polyaniline molecular chain increase with reaction time extending. The best reaction temperature is about 20 °C. The reaction temperature is higher that of pure aniline polymerizing reaction. 3. Active groups in coal such as carboxyl group and phenol hydroxyl group not only play a role of prontonation on ―= group in polyaniline, but also form hydrogen bond with ― NH― group in polyaniline.
