Abstract :In this study, conductive homopolymers of o-chloroaniline, p-bromoaniline and N-methylaniline were synthesized electrochemically in perchloric acidic solution and their properties were analyzed. Initially, the maximum oxidation potential values of these monomer solutions were determined by Cyclic Voltammetry insert ignore into journalissuearticles values(CV);. Their conductive polymers were then synthesized under a nitrogen atmosphere using a potentiostat. FTIR spectra were taken in order to analyze the structural properties of the resulting polymers. Thermogravimetric analysis insert ignore into journalissuearticles values(TGA); was conducted and surface micrographs were taken by a Scanning Electron Microscope insert ignore into journalissuearticles values(SEM);. The conductivity levels of the polymers were determined by the Four Probe technique. Magnetic properties of the samples were analyzed and the conduction mechanisms were examined. Based on the resulting conductivity data, it was concluded that polyinsert ignore into journalissuearticles values(p-bromoaniline); was of polaron structure, whereas polyinsert ignore into journalissuearticles values(o-chloroaniline); and polyinsert ignore into journalissuearticles values(N-methylaniline); were of bipolaron structure. Thermogravimetric analysis results indicated that polyinsert ignore into journalissuearticles values(N-methylaniline); has the highest maximum decomposition temperature, and conductivity measurements revealed that polyinsert ignore into journalissuearticles values(o-chloroaniline); has the highest conductivity level.
