Graphene-related materials (GRMs), including graphene, expanded graphite, few-layered graphene (FLG), graphene oxide (GO), and reduced graphene oxide (rGO), have outstanding electronic, mechanical and thermal properties to be used as multifunctional nanostructured building blocks, which provides them the potential to contribute to many fields of science and technology. We use these materials alone or in combination with polymers in a nanocomposite approach as electrode surfaces and flexible electronics applications.

Defects and functionalization of graphene with side groups have a significant impact on its properties. The presence of defects, such as dislocation dipoles, vacancy defects, and Stone-Wales defects, can strongly affect the morphology, mechanical strength, and thermal transport of graphene. These defects can alter the electronic, chemical, and mechanical properties of graphene,

In addition to defects, the functionalization of graphene with side groups also plays a crucial role in determining its properties. The interaction of side terminal groups with the dispersion medium affects the dispersibility of graphene, while the backbone of a surfactant primarily interacts with graphene via π-π interactions, influencing the functionalization efficiency. Moreover, the functionalization of defective graphene with oxygen and hydroxyl groups can lead to changes in its electronic properties and magnetic moments.

We strive to Understand and control these factors, which are essential for the development of graphene-based materials and devices with tailored properties.
