Controlling Molecular Ordering in Aqueous Conducting Polymers Using Ionic Liquids

Abstract

The molecular ordering of aqueous conducting polymers is controlled using a rational method. By introducing various ionic liquids, which have designed electrostatic interactions to PEDOT:PSS solutions, the evolution of the molecular ordering of the PEDOT is manipulated. Consequently, highly ordered nano structures are achieved with a reduced pi-pi stacking distance of approximate to 3.38 angstrom and, thus, a maximum sigma(dc) of approximate to 2100 S cm(-1)
