Hydrodynamic electrochemical processing of poly(2-methoxy aniline-5-sulfonic acid)

This thesis deals with the electrochemical synthesis of a water soluble polyaniline derivative, 2-methoxy aniline-5-sulfonic acid (2-MAS), under hydrodynamic conditions. The electrochemical characteristics of the monomer (2-MAS) were studied. The effect of electrolyte composition, concentration of monomer and temperature on the polymerization process was investigated in a stationary cell. The electrochemical polymerization of 2-MAS was undertaken at a feed composition of 0.5M 2-MAS in 0.5M ammonium hydroxide (NH4OH) in the flow-through cell system designed for mass production of soluble conductive polymers. With the aid of UV-VIS, GPC and HPLC, the effect of appUed potential, polymerization time and the flow rate through the cell on the hydrodynamic electropolymerization process were investigated.
