Electrodeposition preparation method of a photocrosslinked bio-based coating

Abstract

The invention provides an electrodeposition preparation method of a light-crosslinking bio-based coating. The preparation method comprises the following steps: preparing micellar particles and compound self-assembly micelles particles of coating functional factors from amphiphilic ionic biological macromolecules containing photosensitive groups in a self-assembly manner; forming a film on a medical metal surface by using a potentiostatic electrodeposition technology; carrying out crosslinking on the micellar particles by ultraviolet irradiation crosslinking reaction, so as to obtain a medical biological coating material based on a self-assembly micellar film. The method is simple and convenient to operate, mild in condition and wide in application range.

Description

technical field

[0001] The invention relates to the technical field of combining polymer materials and medical biological coatings, in particular to an electrodeposition preparation method of biological-based coatings. Background technique

[0002] Since the beginning of this century, with the rapid development of science and technology and productivity, people's quality of life has been continuously improved and their life expectancy has been extended. How to improve the recovery efficiency of patients in medical treatment has attracted the attention of the medical community and material workers. The rapid development of biomedical materials provides the possibility to realize this requirement. On the other hand, my country, as the world's most populous country that is heading towards an aging population, has an increasing demand for biomedical materials.

[0003] Among all biomedical materials, biomedical metal materials are widely used in clinical medicine due to their ...
