Building materials, plants, paints, chemicals, and fossil fuels combustions all emanate volatile organic compound (VOC), which influence our health and everyday lives. Therefore, the ability to detect VOCs at room temperature is very essential. This study focused on interdigitated electrode (IDE) sensor based on the hybrid nanoparticles of iron oxide (Fe3O4), polyaniline (PANI) and reduced graphene oxide (rGO) and its sensing mechanism towards 300ppm acetone was investigated. The hybrid material was synthesized through in-situ method and deposited on the IDE using drop-cast method. X-ray diffraction shows that all unary materials were present in the hybrid nanoparticles and the crystallite size calculated was 4.49nm. The response and recovery time for the hybrid material towards 300ppm acetone was 2.73min and 2.67min, respectively which shows a great improvement compared to response and recovery time of single material of Fe3O4. The IDE based on hybrid materials sensor in sensitive and reversible, making it suitable for human health and environmental safety application. © 2021 International Scientific Organization.
