The present disclosure relates to the development of hydrogels with extreme stiffness and high-strength. In particular, an hydrogel comprising poly(2-hydroxyethyl methacrylate) and graphene material with a specific oxidation degree. The hydrogels of the present disclosure may be used in medicine, veterinary or cosmetic, namely as scaffold, cartilage, intervertebral disc and blood contact device such as: catheters, vascular grafts, heart valves, stents, artificial kidneys, artificial lungs, ventricular assist devices or drug delivery system. Uses in other areas can be envisaged, like in soft robotics, packaging, sealing and sensors.
A hydrogel comprising poly(2-hydroxyethyl methacrylate) and at least 1%-5% (w/v) of graphene material, wherein the oxidation degree of the graphene material is between 30-25 (oxygen atomic percentage),
