▎ 摘  要

NOVELTY - Preparing diamond nanoparticle modified on surface of azobenzene polymer whose thermal conductivity can be regulated by light radiation involves performing surface pre-modification of diamond nanoparticle, preparing azobenzene polymer monomer, and grafting azobenzene polymer monomer onto surface of diamond nanoparticle by free radical photopolymerization. USE - Method for preparing diamond nanoparticle modified on surface of azobenzene polymer whose thermal conductivity can be regulated by light radiation. ADVANTAGE - The method has influenced molecular arrangement state of the azobenzene liquid crystal functional group, and realized rapid reversible regulation and control of the heat conductivity coefficient of the diamond nano particle modified on the surface of the azobenzene polymer.
