Abstract

The invention discloses a method for preparing a zinc oxide-doped titanium dioxide nanotube on a pure titanium surface, and belongs to the technical field of material surface modification. The method comprises the following steps: a pretreated pure titanium sample is put on a sample table of magnetron sputtering equipment, and a titanium zinc alloy target is placed opposite to the sample; after the vacuumizing is performed, argon is fed in a vacuum chamber, certain voltage is applied to the alloy target and the sample, and titanium and zinc elements are deposited on the pure titanium surface to form a titanium zinc composite film layer under the effect of plasma bombardment; and then, the anodic oxidation treatment is performed for the composite film layer to prepare the zinc oxide-doped titanium dioxide nanotube. The nanotube, prepared by the method, has excellent infection resistance and osseointegration capacity.

Description

technical field [0001] The invention relates to a method for preparing zinc oxide-doped titanium dioxide nanotubes on the surface of pure titanium, which belongs to the technical field of material surface modification. Background technique [0002] Dental caries, osteoarthritis and other diseases are common and frequently-occurring diseases of middle-aged and elderly people, and they tend to become younger. Artificial prosthesis replacement based on pure titanium is one of the standard operations for end-stage patients to relieve pain and reconstruct tissue function, but loosening and infection after implantation are two major complications that have plagued both doctors and patients for a long time. The above-mentioned complications often lead to operation failure and lead to reoperation, causing patients to suffer physical pain and mental torture, even disability and death. The subsequent medical expenses have brought great mental pressure and heavy burden to many families...
