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.
