Embodiment

[0019] An electrochemical additive manufacturing method for a fluorinated hydroxyapatite bionic flap patterned surface with antibacterial properties, the steps of the method are as follows:

[0020] Step (1): using a pure titanium substrate as a cathode material for electrochemical additive manufacturing;

[0021] Step (2): The electrochemical additive manufacturing reaction unit includes an anode (platinum), a cathode (pure titanium), a reference electrode (saturated calomel electrode), and three electrodes;

[0022] Step (3): The electrolyte consists of three solutions, 0.042M Ca(NO 3 ) 2 , 0.025M NH 4 h 2 PO 4 , 0.001M NaF, the volume ratio of the three solutions is 100mL:100mL:100mL;

[0023] Step (4): adjusting the pH value of the electrolyte to 3;

[0024] Step (5): The electrochemical additive manufacturing reaction uses a constant voltage mode, and the voltage is controlled at -1.6V; nitrogen gas is introduced into the electrolyte during the reaction; the reactio...

Abstract

The invention discloses an electrochemical additive manufacturing method for a fluorinated hydroxyapatite bionic cicada-wing patterned surface with antibacterial property. The fluorinated hydroxyapatite bionic cicada-wing patterned surface prepared by the electrochemical additive manufacturing method provides a non-medication strategy which does not depend on medicine components such as antibiotics, but depends on chemical components and physical morphology to generate a synergistic antibacterial effect; a patient can be effectively prevented from generating a medicine anaphylactic reaction due to the fact that medicine such as the antibiotics are not depended, and the physical burden of the patient is greatly reduced; and the surface not only has the antibacterial performance, but also has good biocompatibility and biological activity.

Description

technical field [0001] The invention belongs to the technical field of bionic engineering and biomedical engineering material preparation, and in particular relates to an electrochemical additive manufacturing method for a fluorinated hydroxyapatite bionic flap patterned surface with antibacterial properties. Background technique [0002] In recent years, the problem of population aging has become increasingly prominent, and orthopedic diseases such as hip joint disease, knee joint disease and intervertebral disease have increasingly plagued the daily life of middle-aged and elderly people. In view of the ever-increasing health care needs of the people, more and more families and society have paid more and more attention to orthopedic implant surgery such as artificial joint replacement surgery. However, there is still a certain proportion of postoperative infection in this type of operation, and infection can cause complete failure of the operation, and even serious consequ...
