Preparation of poly(2-amino thiophenol) nanodiscs by a “combined hard–soft template” approach and characterization

A seed induced chemical oxidative polymerization was used for the preparation of pure poly(2-amino thiophenol) nanodiscs (P2AT-NDs (P)). Two templates, (hard (MCM-41) and soft (β-napthalene sulfonic acid), were utilized for the preparation of the seed, P2AT nanostructures loaded MCM-41. The field emission scanning electron microscopy reveals nanodisc morphology for P2AT (P). X-ray diffraction, current–potential characteristics and electrochemical impedance spectroscopy were used to evaluate the physicochemical properties of P2AT-ND (P). The P2AT-ND (P) exhibits semicrystalline behaviour, good electron transport and lesser charge transfer resistance at the interface as compared to simple P2AT prepared by conventional chemical route.
