Herein we report a electrode in the hybrid  structure of the silver nanowires (AgNWs) with reduced graphene oxide (rGO) deposited on glass or PET substrate. The assembly and contacting in procedures of this hybrid film have been strongly affected by preparation conditions, especially annealing temperature. In this work, we have investigated the effects of thermal annealing on interconnected at nanowire junctions and between AgNWS network and rGO films via their sheet resistance and transmission. The annealing temperature was varied from 120\(^{\circ}\)C to 180\(^{\circ}\)C with 10\(^{\circ}\)C step to find out optimal temperature at which the wires can be joined together. The results show that at 170\(^{\circ}\)C, the sheet resistance and transmission of the hybrid rGO/Ag NW film are \(R_{s} = 10.7\;\Omega\) sq\(^{ - 1 }\) and \(T = 77\)% (at wavelength 550 nm) corresponding to the ratio of direct conductivity to optical conductivity \(\sigma _{DC}/\sigma _{OP} = 126\) which is the best obtained value. It is expected that the hybrid AgNWS/rGO film can replace ITO film in the near future.

A novel hybrid structure sensor based on cobalt carbonate hydroxide hydrate (CCHH) and reduced graphene oxide (RGO) was designed for room temperature NH3 detection. This hybrid structure consisted of CCHH and RGO (synthesized by a one-step hydrothermal method), in which RGO uniformly dispersed in CCHH, being used as the gas sensing film. The resistivity of the hybrid structure was highly sensitive to the changes on NH3 concentration. CCHH in the hybrid structure was the sensing material and RGO was the conductive channel material. The hybrid structure could improve signal-to-noise ratio (SNR) and the sensitivity by obtaining the optimal mass proportion of RGO, since the proportion of RGO was directly related to sensitivity. The gas sensor with 0.4 wt% RGO showed the highest gas sensing response reach to 9% to 1 ppm NH3. Compared to a conventional gas sensor, the proposed sensor not only showed high gas sensing response at room temperature but also was easy to achieve large-scale production due to the good stability and simple synthesis process.
