Abstract
Many studies have been carried out on sensors for detecting hazardous chemicals. In this study, a sensor for detecting the presence of acid was developed and evaluated. The sensor is composed of carbon materials and polyaniline, which is a conductive polymer. Various candidate carbon materials for the sensor were examined, including graphite, reduced graphene oxide (rGO), and graphene nanoplatelets (GNP). From characterization of carbon material-polyaniline and acid reaction test, it was confirmed that the GNP was the best carbon material for the acid sensor. For practical use, the GNP–polyaniline
composite was coated on PET to enable a flexible sensor.
