This book explains synthesis and characterizations of PANI based nanocomposite materials and their significant applications in various fields including treatments of industrial effluents. Three types of nanocomposites namely; PANI-Ti(IV)W, PANI-Ti(IV)As and PANI-Zr(IV)S were synthesized by using very simple chemical route. The experimental conditions, including mixing volume ratio of reactants, pH and temperature were established for their synthesis. The nanocomposites showed improved conducting behavior, higher ion uptake capacity along with chemical and thermal stability. On the basis of Kd...
