Description
Summary:Conductive polymers are widely used in many applications such as sensors, solar cells, diodes, electrodes, and actuators. Among of conductive polymers, Polyaniline (PANI) has gained more interests due to high environmental stability, electrical conductivity, easy processability, and low cost. Synthesis of PANI with different molar ratios between Dodecylbenzenesulfonic acid (DBSA) and Aniline (An) ([DBSA]/[An]) at 0.5, 1.0, and 1.5 were investigated. The increased molar ratio of surfactant affects to improvement in higher electrical conductivity of 18.91 × 10−2 S/m. This is due to the increasing of doping in PANI-DBSA which can be obtained by Fourier Transform Infrared Spectroscopy (FTIR). At high molar ratio, thorn-liked structure and smooth surface of PANI are observed compared to irregular structure at low molar ratio. Moreover, the chemical structures of PANI-DBSA are investigated by Solid-state Nuclear magnetic resonance spectroscopy (NMR).
