Abstract

Flexisense: Films of graphene oxide and reduced graphene oxide are printed onto a flexible plastic surface (see picture), using inkjet techniques, which are used to detect chemically aggressive vapors such as NO2 and Cl2. Vapors in the 100 ppm500 ppb concentration range can be detected in an air sample without the aid of a vapor concentrator. "Chemical Equation Presented"
