Preparation and Properties of Hydrogel for 3D-Printed Cartilage Repair

As a new type of medical material, natural polymer hydrogel can be widely used in the field of orthopedics and plays an important role in bone tissue engineering scaffold materials. This article mainly introduces the ideal requirements of bone tissue engineering scaffold materials, and elaborates the development status of 3D printing technology and biomedical material hydrogels. In this paper, a new kind of nanocomposite hydrogel material was prepared by combining GO and hyaluronic acid with the thermal gelation property of methyl cellulose and modified polyethylene glycol as crosslinking agent, and its physical and chemical properties were studied. By changing the concentration of graphene oxide solution, in order to obtain a better gel preparation program.
