The unique properties of graphene have directed researchers to study and characterize this new material. Graphene production and graphene based materials have been widely explored and developed in the past decade. Most research has aimed at developing scalable, environmentally friendly, and cheap procedures to produce defect-free graphene that can be used in various applications such as mechanical properties enhancement and multifunctional material. The challenge is processing such material on a scale suitable for engineering applications such as advanced photonics and advanced electronics. In this study, we investigate a new processing technique based on Langmuir-Blodgett (LB) Technique. We managed to produce a mono-graphene film as well as a multilayer graphene film. Besides, we investigate graphene-graphite transition by measuring the electrical conductivity of the produced film. Moreover, we managed graphene/ Poly-methyl methacrylate (PMMA) nanocomposite with thickness up to a few nanometers. We characterized the mechanical, optical, and electrical properties of such films and compared the performance to similar material processed by more expensive film preparation methods.
