| Summary: | 碩士 === 中國文化大學 === 化學系應用化學碩士班 === 102 === Novel flexible humidity sensors were fabricated by layer-by-layer (LBL) covalently bonding graphene oxide (GO) to a gold electrode on a plastic substrate using a peptide chemical protocol and then reducing in-situGO film to a partially reduced GO film. The effect of the duration of reduction of GO film on the electrical and humidity propertiesof the reduced GO film was investigated. This flexible impedance-type humidity sensor exhibited a strong water resistance, a wide working range of humidities, a short response/recovery time, a weak dependence on temperature and good long-term stability. The different complex impedance plots obtained at low and high relative humidity indicated that the ions dominate the conductance of the anchored partially reduced GO film.
