PREPARING METHOD OF HEAT RADIATING POWDER AND FILM USING DIFFUSION AND SCATTERING OF HEAT AND HEAT RADIATING POWDER AND FILM PREPARED THEREBY

摘要

A method for producing a heat dissipation powder includes the steps of mixing a nanoparticle precursor containing a metal salt with water to produce a first composite nanoparticle sol, mixing a modifier containing a silane compound into the first composite nanoparticle sol to form a second composite nanoparticle sol A step of forming a composite nanoparticle sol, a step of forming a composite nanoparticle sol, a step of coating the above-mentioned second composite nanoparticle sol on a carrier particle containing at least one of silicon carbide and boron nitrate to form a third composite nanoparticle sol And drying the third composite nanoparticle sol.
