Embodiment 1

[0025] Step 1: Material cleaning. A square sheet of pure titanium with a thickness of 0.1 mm and a purity of 99.9% was used as the substrate, ultrasonically cleaned with absolute ethanol, acetone, and deionized water for 10 min, wiped with filter paper, and air-dried for later use;

[0026] Step 2: surface acid treatment. Using HF and HNO at a volume ratio of 1:1 3 The mixed solution was polished for 5 minutes, the surface was rinsed with deionized water, and dried in a constant temperature drying oven at 50 °C for 15 minutes for later use;

[0027] Step 3: Alkaline heat treatment. The acid-treated pure titanium was placed in a plastic bottle filled with 2 mol / L NaOH solution, the material was completely soaked in the NaOH solution, and placed in a constant temperature drying oven at 80 °C for 72 hours of alkali heat treatment, and then ultrasonicated with deionized water Clean the surface for 10 minutes, and dry it in a constant temperature drying oven at 50 °C for 15 min...

[0031] Step 1: Material cleaning. A square sheet of pure titanium with a thickness of 0.1 mm and a purity of 99.9% was used as the substrate, ultrasonically cleaned with absolute ethanol, acetone, and deionized water for 10 min, wiped with filter paper, and air-dried for later use;

[0032] Step 2: surface acid treatment. Using HF and HNO at a volume ratio of 1:1 3 The mixed solution was polished for 8 minutes, the surface was rinsed with deionized water, and dried in a constant temperature drying oven at 50 °C for 20 minutes for later use;

[0033] Step 3: Alkaline heat treatment. The acid-treated pure titanium was placed in a plastic bottle filled with 6 mol / L NaOH solution, the material was completely immersed in the NaOH solution, and placed in a constant temperature drying oven at 80 °C for 24 hours of alkali heat treatment, and then ultrasonicated with deionized water Clean the surface for 10 minutes, and dry it in a constant temperature drying oven at 50 ℃ for 20 mi...

Embodiment 3

[0036] Step 1: Material cleaning. A square sheet of pure titanium with a thickness of 0.1 mm and a purity of 99.9% was used as the substrate, ultrasonically cleaned with absolute ethanol, acetone, and deionized water for 10 min, wiped with filter paper, and air-dried for later use;

[0037] Step 2: surface acid treatment. Using HF and HNO at a volume ratio of 1:1 3 The mixed solution was polished for 10 minutes, the surface was rinsed with deionized water, and dried in a constant temperature drying oven at 50 °C for 15 minutes before use;

[0038] Step 3: Alkaline heat treatment. The acid-treated pure titanium was placed in a plastic bottle filled with 8 mol / L NaOH solution, the material was completely immersed in NaOH solution, and placed in a constant temperature drying oven at 80 °C for 48 hours of alkali heat treatment, and then ultrasonicated with deionized water Clean the surface for 10 minutes, and dry it in a constant temperature drying oven at 50 °C for 15 minutes...

Abstract

The invention discloses a preparation method of self-assembly silanization of a pure titanium metal surface; according to the invention, various silane coupling agents are grafted on a titanium surface; various active groups, such as amino, hydroxyl, and carboxyl groups, are introduced into the pure titanium surface so as to functionalize the titanium based surface and maintain the porous structure of the substrate; the preparation method of the invention is easy to control, simple in operation, and easy to popularize; and the material is expected to be used in the preparation of in-vitro tissue engineering bone scaffolds and in-vivo materials for repairing bone defects.

Description

technical field [0001] The invention relates to surface modification of pure titanium metal, in particular to a preparation method for self-assembly silanization of pure titanium metal surface. Background technique [0002] Pure titanium and titanium alloys have good biocompatibility, physical and chemical properties, and high mechanical strength. They have been widely used in artificial joints, dental implants, bone replacement and repair materials, etc., but they also have poor biological activity and lack of osteoinductive properties. Effect, no strong chemical combination with the surrounding tissue, long healing time and other shortcomings, can not meet the clinical requirements of fast healing and high osseointegration strength, thus affecting the application of titanium and titanium alloy implants. In a certain physiological environment, medical materials are often required to have good biological activity, so as to achieve chemical bonding with bone tissue, modify th...
