Polyaniline Nanofibers: Facile Synthesis and Chemical Sensors

Jiaxing Huang, Shabnam Virji, Bruce H. Weiller, Richard B. Kaner

Open publisher page 1,662 citations

Abstract

Polyaniline nanofibers with uniform diameters between 30 and 50 nm can be made in bulk quantities through a facile aqueous/organic interfacial polymerization method at ambient conditions. The nanofibers have lengths varying from 500 nm to several micrometers and form interconnected networks. Thin films made of the nanofibers have superior performance in both sensitivity and time response to vapors of acid (HCl) and base (NH3).
