Abstract
A graft polymer is provided, which includes a polymer backbone with a plurality of hydroxy groups, protection group modified histidine grafted onto the side of the polymer backbone, and hydrophilic polymer having terminal reactive group grafted onto the side of the polymer backbone. The graft polymer coating can be applied to metal material to form a composite material, which can be implanted into an organism to reduce adhesion problems.

A composite material, comprising:
- a metal material;
- and
- a graft polymer coated on the metal material, wherein the graft polymer includes:
- a polymer backbone with a plurality of hydroxy groups;
- a protection group modified histidine grafted onto the side of the polymer backbone;
- and
- a hydrophilic polymer having a terminal reactive group grafted onto the side of the polymer backbone,
- wherein the graft polymer is adsorbed to the surface of the metal material by the protection group modified histidine.
