This project addresses the detection of VOC gases like Acetone and Ethanol, crucial for public health and environmental safety due to their harmful effects. A graphene-chitosan gas sensor is developed and analyzed for response, response time, and recovery time. A binder is prepared by mixing chitosan and acetic acid, followed by preparation of graphene paste. Electrodes are deposited on Kapton film, and graphene paste is applied as a sensing layer. SEM and Raman characterizations confirm the sensing material. Results show higher response to acetone than ethanol, with faster response time for acetone. The novel sensor demonstrates better response for acetone detection, offering potential for environmental and health monitoring.
