Effect of Titanium Dioxide on Adhesion and Conductivity Behavior of Polyaniline/Alkyd Composite for Solar Cell Application

This study attempts to improve the adhesion and conductivity of polyaniline (PAni) by incorporating an alkyd and titanium dioxide (TiO 2 ), respectively. PAni with different TiO 2 content (10, 20, and 40%) are synthesized through chemical oxidation method by using aniline (Ani) monomer, dioctyl sodi...
