1-dimensional polymer nanostructure from aromatic diamine.

In recent years, increasing research interest has focused on the aromatic polymers such as polyaniline (PANI), polypyrrole (PPy), polythiophene etc. due to their conductive nature and good environmental stability which offer wide potential applications including electrocatalyst, energy storage, electrochromic display, antistatic and anticorrosive materials, sensors. In this regard, one-dimensional (1D) nanostructure morphologies like nanorods, nanowires, nanotubes, nanofibers, nanoneedles and nanobelts are found to be highly desirable owing to their tunable morphology, higher surface area, fast chemical kinetics and rapid doping-dedoping capability. In comparison to monoamine polymers, aromatic diamine polymers offer unique multifunctionality because of one free amino group per repetitive unit on the polymers. In this work, we synthesized 1D polymer nanostructure from poly (para-phenylenediamine), which is an aromatic diamine polymer. Potassium persulfate (K₂S₂O₈, KPS) was used as oxidant and methyl orange as structure-directing template. These 1D fiber-like polymer nanostructures exhibit rectangular opening and partial crystallinity. [ABSTRACT FROM AUTHOR]
