Polyether ether ketone substrate composite material and its preparation method and application |
| abstract |
The invention relates to a polyether ether ketone base composite material and a preparation method and application thereof. The polyether ether ketone substrate composite material includes a polyether ether ketone substrate, the polyether ether ketone substrate includes a first surface and a second surface, and the first surface and the second surface are connected to each other to form the polyetherether ether The entire outer surface of the ketone substrate; the first surface is provided with a polydopamine layer and a polydopamine-modified nano-hydroxyapatite layer in sequence, and the second surface is provided with a gel layer; the gel layer is passed through polyethylene glycol Alcohol diacrylamide and 2-methacryloyloxyethyl phosphorylcholine were prepared by gelation reaction. The polyether ether ketone base composite material has good lubricity, compressive strength and osteogenesis ability. |
