Example Embodiment

[0023] The present invention will be described in further detail below with reference to the examples and the drawings, but the embodiments of the present invention are not limited thereto.

[0024] The reagents used in the examples can be purchased from the market without special instructions.

[0025] Example 1-11 The TAC enhanced polyether ether ketone composite coating is prepared by:

[0026] (1) Chitosan solution: 0.5 g of chitosan, 5 ml of ice acetic acid and 500 ml deionized water;

[0027] (2) The above 50 ml chitosan solution was mixed with 50 mL of ethanol, and then 1 to 5 gpeek powder (20-30 μm) and 0.01 to 0.2 g of TAC (50-100 nm) were added to give a mixed solution;

[0028] (3) The mixed solution obtained by step (2) was dissolved by ultrasonic dispersion, stirred and dissolved for 7 h, resulting in a nano suspension solution.

[0029] (4) Put the cathode (pure titanium) and an anode (PT) electrode material into the nano suspension solution obtained by step (3), ele...

Abstract

The invention belongs to the technical field of biological materials and particularly discloses a tantalum carbide reinforced polyether-ether-ketone composite coating and a preparation method and application thereof. The method comprises the following steps that (1), after a chitosan solution and ethanol are uniformly mixed, PEEK powder and nanometer TaC are sequentially added in to obtain a mixed solution, and nanometer suspension liquid is obtained by ultrasonic dispersion; and (2), a cathode material and an anode material are put in the nanometer suspension liquid obtained in the step(1), direct current is introduced in, and the nanometer TaC reinforced polyether-ether-ketone composite coating is obtained through deposition. According to the tantalum carbide reinforced polyether-ether-ketone composite coating and the preparation method and application thereof, a PEEK coating is prepared on substrates of titanium and alloy thereof, stainless steel and the like through a cathode electrodeposition method, and nanometer TaC particles are introduced in a PEEK material, the osteogenesis performance of PEEK can be enhanced, and the coating prepared through cathode electrodeposition is short in production time, simple in equipment, low in price and wide in application prospect.

Description

technical field [0001] The invention belongs to the technical field of biomaterials, and in particular relates to a tantalum carbide reinforced polyetheretherketone composite coating and a preparation method and application thereof. Background technique [0002] Titanium and its alloys in artificial joint replacement materials have excellent properties, such as low density, high specific strength, good electrochemical corrosion resistance, relatively low elastic modulus and good biocompatibility. Widely used in biomedical engineering. Titanium and its alloys have the advantages of low density, high specific strength, good electrochemical corrosion resistance, low elasticity, and good biocompatibility. They are frequently used as structural components in the aerospace, automotive, petrochemical and marine industries, as well as in chemical and biomedical engineering. The main disadvantages of all titanium alloys are poor wear resistance, high coefficient of friction (COF) a...
