Graphene is one of the most popular
materials because of its potential for a wide range of applications. It has a
hexagonal lattice with stability at room temperature. Graphene is considered
highly sensitive and functionalized with a linker molecules due to its 2D
structure. Cohesive forces between graphene sheets can only be reduced through
surface modification. Functionalization of can alter chemical and physical
properties while providing additional functions. It is more widely used in
sensors, electronic devices, and batteries. Surface functionalization has the
potential to be used as nanocomposite materials.
