A hydrogel is a three-dimensional (3D) hydrophilic polymer network with several unique
characteristics, including hydrophilicity, swelling, micro-nanosized pores, and softness. These
characteristics of hydrogels make them very useful for various biomedical applications, such
as tissue augmentation, drug delivery, and tissue engineering scaffolds [1]. The
inclusion/incorporation of nanoparticles in three dimensional polymeric structures is an
innovative means for obtaining multicomponent systems with diverse functionality within a
hybrid hydrogel network. Nanoparticle-hydrogel combination adds synergistic benefits to the
new 3D structures. Nanogels as carriers for cancer therapy and injectable gels with improved
self-healing properties have also been described as new nanocomposite systems [2]. Among
nanoparticles, nanoparticle graphene and its derivatives are the most important. The
traditional hydrogel is composed of cross linked organic polymer, but its poor mechanical
property and stability limit its wide application. Graphene-based hydrogels (including
graphene oxide hydrogel and reduced graphene oxide hydrogel in this paper) can solve this
application limits because of its excellent properties [3]. In this study, we synthesized
hydrogels that are nanocomposite in nature and are loaded with graphene oxide nanoparticles
that enhance the hydrogel in terms of thermal resistance and mechanical properties and
increase and improve its absorption surface for drug delivery as well as medical applications
and various industries.
