| titleOfInvention | Degradable metal surface gradient polymer layer and preparation method thereof |
| abstract | The invention relates to a degradable metal surface gradient polymer layer and a preparation method thereof, wherein the degradable metal surface gradient polymer layer comprises an interface layer and a polymer layer on the surface, and the preparation method comprises the steps of adding dopamine into a micro-arc oxidized electrolyte, carrying out micro-arc oxidation on the degradable metal, depositing a poly-dopamine film layer on the surface of the degradable metal while carrying out micro-arc oxidation, introducing active functional groups of amido and hydroxyl, further initiating polymerization of different types of monomers by using the active functional groups by adopting a front-end polymerization method, and preparing the polymer layer which is in gradient distribution along the specific direction of a matrix profile; the polymer layer with the polymer molecular weight, the degradation rate and the hydrophilicity and hydrophobicity in gradient distribution is prepared by controlling the type and the content of the monomer, the concentration of the initiator, the polymerization temperature and the polymerization time, so that the prepared degradable metal is degraded in a gradient controllable manner along a specific direction under the protection of the polymer layer. |
