Titanium alloy containing antibacterial coating as well as preparation method and application thereof

The invention discloses a titanium alloy containing an antibacterial coating as well as a preparation method and application thereof. The titanium alloy deposited with nano-silver antibacterial coating on the surface is prepared by the following steps: preprocessing and sterilizing the surface of titanium alloy; then soaking the titanium alloy in a dopamine hydrochloride solution with mass-volume concentration of 1-10mg / mL for 12-36h to obtain titanium alloy deposited with a polydopamine thin film layer on the surface; and finally soaking the titanium alloy in a silver nitrate solution which is 5-100mmol / L in concentration for 12-36h. According to the titanium alloy disclosed by the invention, the titanium alloy is connected to silver nanoparticles by virtue of adhesion from self-polymerization of dopamine and adsorbed silver ions are reduced into nano-silver in situ through weak reducibility of the dopamine. Because of broad-spectrum antibacterial capacity of the nano-silver, an excellent antibacterial effect can be achieved with relatively low effect concentration. The invention provides new thinking for antibacterial modification of the titanium alloy, and can effectively promote application of a titanium alloy implant material in the fields of bone tissue repair and regeneration.
