Abstract Exposure to high amounts of volatile organic compounds (VOC) in the short term can cause headaches, dizziness, worsening asthma symptoms, vomiting, and eye, nose, throat irritation. Thus, a gas sensor is needed detect VOC gases. Chitosan as nonconducting polymer was used an alternative binder for thick film sensors this study. dissolved acetic acid produce solution mixed with graphene nanoflakes make sensor. Two chitosan recipes were study investigate their performance VOCs acetone ethanol. A single layer double deposited effects on sensing. Single layers had little effect sensing response ethanol vapor. Results revealed that prepared by B responded better than value achieved T2‐2‐S1(3) and, T2‐2‐S1(1) 1.0579 1.0532, respectively. In addition, outstanding performances, terms linearity repeatability characteristics.
