Polyaniline Emeraldine Salt(ES), which is commonly used as a conducting polymer, is widely studied for its advantages of synthesizing highly conductive polymers by controlling the polymerization process. However, highly conductive ES has a problem of difficulty in processing due to its difficulty in controlling polymerization and high crystallinity. Therefore, to solve these drawbacks, the ES is dedoped to form a Emeraldine Base(EB), which has the advantage of solution processing, polyaniline polymerization with nanostructure, and thus improves crystallinity. In this study, using Octyltrimethyl Ammonium Bromide (OTAB), ES was polymerized with microemulsion polymerization, and nanofiber EB form was observed with SEM image at optimized OTAB concentration by dedoping with NH3OH solution. Furthermore, ES was dedoped with hydrazine monohydrate to synthesize polyaniline nanofiber in the form of a Leucomeraldine Base(LB), and the analysis was conducted through FT-IR, UV-Vis absorption. |
