ABSTRACT
The organic/inorganic hybrid nanocomposites, in particular, organic conducting polymer (OCP)-based hybrid nanocomposites, constitute emerging advanced materials combining the unique features of inorganic and organic components. This chapter explores the state-of-the-art nanocomposites based on OCPs, mainly polyaniline (PANI) and titanium dioxide (TiO2) nanoparticles, and the appropriate methodology to develop new nanocomposites with improved properties. The nanocomposites of OCPs have been divided into two categories, that is, nanocomposites with organic materials and nanocomposites with inorganic materials, and both have a different synthesis process. The synthesis of PANI can be achieved by different procedures that are usually electrochemical and chemical routes. TiO2 exhibits many prominent characteristics such as chemical and electrical properties. These properties make it attractive and suitable for many applications. The chemical methods that are commonly used for the fabrication of PANI/TiO2 nanocomposites are: chemical oxidation method, hydrothermal method, sol–gel method. In situ polymerization is the major synthesis technique used for the synthesis of PANI/TiO2 nanocomposites.
