Abstract

The invention provides a surface functionalized carbon fiber reinforced polyether-ether-ketone dental composite material. The surface treatment of the carbon fiber reinforced polyether-ether-ketone composite material is carried out by sulfonation and functionalization of graphene oxide to obtain a surface functionalized carbon fiber reinforced polyether-ether-ketone composite material coated witha graphene oxide functional layer, the functional layer has strong binding force to a substrate, is not easy to fall off, and can effectively change the surface geometry and surface functional group composition of the carbon fiber reinforced polyether-ether-ketone composite material, the carbon fiber reinforced polyether-ether-ketone composite material is given with a new surface topography and surface properties, the biocompatibility and osteogenicity are increased, the application in medical materials is increased, the operation method of the invention is simple and easy, the surface treatment condition is mild, and the method is suitable for large-scale promotion and application, and has high medical value.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to the technical field of dental materials, and more specifically relates to a surface functionalized carbon fiber reinforced polyether ether ketone dental composite material and a preparation method thereof. Background technique [0002] Due to the non-renewability of teeth, once damaged, implant materials can only be selected for repair or replacement. Most of the dental implant materials used clinically in the prior art are titanium implant materials, but the elastic modulus between titanium metal and bone tissue There is a huge difference, and it has metal allergies, which affects normal use. [0003] Polyether ether ketone is a kind of fully aromatic semi-crystalline thermoplastic special engineering plastics, which has excellent high temperature resistance, wear resistance, hydrolysis resistance, chemical corrosion resistance, etc., easy extrusion and injection moldi...
