Thin film pallet polyaniline sensor for explosive detection

摘要

Detection of ammonia & nitric oxide can be used for detection of explosives present in a particular area. This study deals with the detection of nitric oxide, ammonia with the help of polyaniline thin film. Thin film of polyaniline is made by spin coating technique. Detailed study of conductivity changes in thin films on exposure to ammonia & nitric oxide is carried out. Thin film preparation, instrumentation in experimental set-up is discussed in detail. Time domain analysis of thin film sensor is also studied.
