Preparation Poly 2-hydroxy aniline Thin Film by Chemical Bath Deposition Technique for Ammonia Vapor Sensor

Poly 2-hydroxy aniline organic Semiconductor polymer was prepared using chemical bath deposition technique through oxidation polymerization by adding potassium per sulfate concentration of (0.1M) to (0.2M) of 2-hydroxy aniline at room temperature, The polymer was deposited on glass substrate, Structural, optical properties of thin film were studies and sensing to NH3 vapor.
