摘要：

This paper presents a study of the formation of graphene layers by Langmuir-Blodgett (LB) technique. The effect of subphase pH and temperature on the graphene Langmuir isotherms are investigated. Also, the influence of subphase conditions on the surface potential of a monolayer was reported. A variation in the pH of the water subphase can lead to change in the electrostatic interactions that influence the compression of the layers. The mechanical characteristics of graphene layers variation under the influence of the subphase pH and temperature was investigated. Langmuir layers assembly is a useful method to manipulate the distribution of graphene layers at the air-water interface. Successful deposition of graphene layers at the air-water interface on a silicon substrate was performed by using Langmui-Schaefer (LS) technique.
