A laminate includes a substrate, a self-healing layer on the substrate and having a thickness of greater than or equal to about 50 micrometers, a protective layer between the substrate and the self-healing layer, and a surface layer on the self-healing layer and having a thickness of about 20 nanometers to about 300 nanometers, wherein the self-healing layer has a first elastic modulus and the protective layer has a second elastic modulus, wherein the second elastic modulus is about 1.2 times to about 50 times greater than the first elastic modulus, and wherein the surface layer has a friction coefficient of less than or equal to about 1.

An eight-arm star-shaped thermoplastic elastomer copolymer and a preparation method therefor; a polystyrene-polyisoprene lithium compound and a polystyrene/diphenylethylene-polyisoprene lithium compound are synthesized by using active anionic polymerization, and the compounds are used for a coupling reaction with octenyl polyhedral oligomeric silasesquioxane to obtain the copolymer. The method has the characteristics of convenient operation, high reaction efficiency, mild reaction conditions, and few side reactions. The structure and molecular weight of the prepared eight-arm star-shaped polymer are controllable, and the molecular weight distribution is narrow. A polymer segment obtained by the copolymerization of diphenylethylene (DPE) and styrene (St) is used as a hard segment, which enables the eight-arm star-shaped thermoplastic elastomer copolymer to have more outstanding mechanical properties. At the same time, a polymer segment composed of DPE and St units has a higher glass transition temperature than polystyrene, which increases the upper limit usage temperature of the eight-arm star-shaped copolymer.
