Abstract

A composite material is disclosed including: a first material including a plurality of crosslinked first polymer chains including a plurality of first polymer monomeric units; a coating layer on the surface of the first material, wherein the coating layer includes a plurality of adhesion polymer chains, wherein the plurality of adhesion polymer chains includes a plurality of the first polymer monomeric units and a plurality of first bond-forming units, wherein the adhesion polymer chains are interwoven with the first polymer chains; and a second material including a plurality of second polymer chains, wherein the coating layer is disposed in-between the first and the second material and contacting the surface of the first and the second material, and a portion of the second polymer chains includes a plurality of second polymer monomeric units and second bond-forming units; wherein the first and the second bond-forming units form one or more bonds.
