Inkjet Printing of Conducting Polymer Nanomaterials

This chapter focuses on the most recent developments in inkjet printing of conducting polymer nanomaterials. The aim of this effort is to elucidate this subject to the readers with a broad range of topics including inkjet-based patterning resolution, strategies to disperse and suspend conducting polymer nanomaterials in liquid, sensing performances of the devices fabricated by inkjet printing, and other applications that utilize inkjet printing of conducting polymer nanomaterials. The chapter details the inkjet printing of polyaniline, and presents a brief overview on the chemical, electrochemical, and electrical properties as well as the synthesis of polyaniline. The proportions of the amine and imine nitrogen atoms present in polymer structure determine the oxidation state of polyaniline. Cyclic voltammetry (CV) is an effective tool for studying the electrochemical properties of many materials, and hence it is often used to examine the redox chemistry of polyaniline.
