Abstract: An experiment was done for the synthesis of the two types of polyaniline one is with the solvent and the other is without the solvent, after that we dry in the vacuum oven, which gives the two different types of morphologies. The polyaniline was prepared by the chemical oxidative polymerization method. For the characterisation of the polyaniline here we use scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy. Polyaniline is easily synthesised and available at a low cost. The prepared polyaniline has shown the amorphous nature of material.
