Abstract: A composite material is described, including a first material comprising a first polymeric network; a second material comprising a second polymeric network; and an adhesion polymeric network comprising a plurality of adhesion polymer chains joined together by a bonding force and interwoven with the first and second polymeric networks to adhere the first and second materials together, where the adhesion polymeric network is not covalently bonded with the first or second material. Methods of making such composite material are also described.
