Abstract
The purpose of this research is to discuss the mechanism of the PAni of PS/PAni core-shell is in a dedoping process in ammonium hydroxide and replaced with organic acids in a redoping process by using UV-Vis spectrum experiment. And PS/PAni chemical structure were changed after reaction were confirmed by the FTIR experiment.
Three different feasible ways to remove dopant and dope acid of the PAni of PS/PAni core-shell particle. Dedoping and redoping process of the PAni were PS/PAni core-shell latex in solution, PS/PAni core-shell packing immersed in solution, and PS/PAni thin film immersed in solution. After redoping process PS/PAni core-shell thin film were made by heat. And the film formation were observed by SEM. Beside this, the conductivity of film was convert by measured resistance and the thermal stability of film after redoping process were discussed in the high temperature by measuring the change of the resistance.
The result shows that redoping process in PS/PAni core-shell packing was developed higher conductivity and better thermal stability film. All of the reaction process still in water phase. And the preparation of PS/PAni conductive film is easily.
