NOVELTY - Preparing double polymer shell/nanoparticle core composite material having optically controlling thermal conductivity coefficient, comprises (i) dissolving nanoparticles, monomer, butyl methacrylate, cyanoisopropyl dithiobenzoate and 2,2-azobisisobutyronitrile in anisole and configuring as a mixed solution, (ii) processing the mixed solution with four freeze-pump-thaw cycles and sealing under nitrogen, (iii) placing the mixed solution in an oil bath at a preset temperature to react for a preset time, (iv) polymerizing, and dropping the mixed solution containing the double polymer shell/nanoparticle core composite material into cold methanol for precipitation, (v) re-dispersing the precipitated product in dichloromethane, and dropping into cold methanol for secondary precipitation, and (vi) recrystallizing the precipitate three times in cold methanol, and drying in a vacuum oven at preset temperature for preset time to obtain the final product. USE - The method is useful for preparing double polymer shell/nanoparticle core composite materials. ADVANTAGE - The double polymer shell/nanoparticle core composite material is capable of adjusting and controlling thermal conductivity coefficient by changing the type of the radiation light.
