Preparation Poly 4-Bromoaniline Thin Films by Electro Deposition Technique for Hydrogen gas sensor

Thin films of Poly 4-bromoaniline organic Semiconductor polymer were prepared using electro deposition technique through oxidation polymerization by adding (2ml) HCl concentrated and (50) ml of Ammonium per sulfate concentrated (0.05M) to (50)ml of 4- bromoaniline (0.04M) at room temperature, The polymer was deposited on Silicon n-type substrate, Structural and optical properties of The thin films were characterized by technique: X-ray diffraction (XRD), (FE-SEM), Fourier transform infrared (FT-IR) spectroscopy, Field emission scanning electron microscopy, uv-visb spectroscopy and sensing of thin film to H2 gas.
