Abstract |
Alternative materials such as hybrid structures of the graphene/carbon nanotube (CNT) show excellent combination of electrical, optical and structural properties fit for the transparent display industry. In this research study, a simple method is introduced to assemble a hybrid structure film between monolayer graphene and carbon nanotube (CNT). This research focuses on the effect of changing the concentration ratio between graphene and carbon nanotube (CNT) to provide high electrical conductivity to films while maintaining optical transparency for applications where these key properties are desired. The results of the electrical conductivity and sheet resistance were detected for all prepared hybrid samples using UV-Spectroscopy and Two-point measurements methods, respectively. It was found that Comparison of the data shows that when the concentration of CNTs decreases, the transparency increases and the film conductivity decreases. Direct graphene spray coating onto glass substrates has a big advantage for transparent electrical films applications. The efficiency of this film is based upon the electrical conductivity, optical transparency also thermal conductivity of the film. The samples have optical transparent ranges between 54%T to 96%T and are also considerably transparent.CNTs and GNPs are efficient material for the hybrid structure.To have high quality uniform films on glass substrates, spray coating technique was used.
