Improvement of properties of polyaniline by changing the reaction conditions

In this work polyaniline composite and nanocomposites were successfullysynthesized in Aqueous solution by using ammonium persulfate ((NH4)2S2O8) as anoxidant in the presence of hydroxyl propyl cellulose (HPC) as stabilizer at 0 and 25 ⁰creaction temperature. The influence of reduced reaction temperature on polyanilineproperties were also addressed. The morphology of the products have been determined byusing scanning electron micrograms (SEM). Also Fourier transform infrared spectroscopy(FTIR) and X-Ray diffraction (XRD) have been used to study the characteristics ofproducts such as chemical structure. The results indicate that the morphology, particlesize, homogeneity and conductivity of products are dependent on the synthesisconditions. The SEM results indicate that particle size of products decrease andhomogeneity increases by using hydroxyl propyl cellulose as surfactant and reducing thereaction temperature. Based on this work, reducing reaction temperature can produceenhanced polyaniline properties.
