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.
