improvement of properties of polyaniline by changing the reaction conditions

in this work polyaniline composite and nanocomposites were successfully synthesized in aqueous solution by using ammonium persulfate ((nh₄)₂s₂o₈) as an oxidant in the presence of hydroxyl propyl cellulose (hpc) as stabilizer at 0 and 25⁰c reaction temperature. the influence of reduced reaction temperature on polyaniline properties were also addressed. the morphology of the products have been determined by using scanning electron micrograms (sem). also fourier transform infrared spectroscopy (ftir) and x-ray diffraction (xrd) have been used to study the characteristics of products such as chemical structure. the results indicate that the morphology, particle size, homogeneity and conductivity of products are dependent on the synthesis conditions. the sem results indicate that particle size of products decrease and homogeneity increases by using hydroxyl propyl cellulose as surfactant and reducing the reaction temperature. based on this work, reducing reaction temperature can produce enhanced polyaniline properties.
