摘要
In this work, the possibility of manufacturing chemiresistive gas sensing devices by inkjet printing different LPE (Liquid Phase Exfoliation) graphene suspensions, formulated in standard organic solvents or aqueous mixtures, on rigid and flexible substrates has been studied. The sensing film has been obtained by printing a different number of graphene layers, depending on the specific ink/substrate system. The device performances have been investigated upon exposure to different concentrations of NO2 at ambient pressure and temperature, addressing the device-to-device variation as function of the number of printed layers and the base conductance.
