Antibacterial activity and Electrical properties of Prepared Graphene Oxide GO Hybrid Cupper Phthalocyanine (CuPc)

Abstract

GO samples were prepared by Hummer‘s method. The Electrical properties of polymer composite Go-CuPc (graphene oxide-cupper phthalocyanines) prepared by spin coating technique were studied. Three different ratio of the prepared graphene oxide added to the pure cupper phthalocyanines (10%, 15%, 20%). It was found that there was a clear increasing in the concentration of carriers and a decreasing in the values of mobility at room temperature with increasing of doping ratio, the electrical conductivity increased with the increase of the concentration of GO, the value of activation energy decreased for all (GO/CuPc) thin films with adding concentration of GO. The antimicrobial properties of Graphene Oxide Modified Cupper Phthalocyanine were evaluated against Staphylococcus aureus, Gram-positive bacterium and sydomonus, Gram-negative one. Bacteriological tests were performed in Muller Hinton solid agar plates with different concentrations of graphene oxide particles. The inhibition zones as a function of added graphene oxide where studied, the results show that as the concentration of graphene oxide increased the inhibition zone increased also against both types of bacteria. When the ratio of added graphene oxide was (15%) maximum inhibitionzone has been calculated.
