GRAPHENE COATED WITH ALUMINUM OXIDE, PREPARATIVE METHOD THREREFOR AND NANO-COMPOSITE CONTAINING THE SAME |
摘要 |
<p>The present invention relates to a graphene coated with aluminum oxide as a nanosheet having high thermal conductivity and low electrical conductivity, to a method for manufacturing the same, and a nanocomposite material including the same. Provided are graphene coated with aluminum oxide having electrical conductivity of 10^(-2)~10 S/cm and thermal conductivity of 10-500 W/m·K at the pressed density of 0.6-0.9 g/cm3, a method for manufacturing the same, and a nanocomposite material including the same. According to the present invention, a nanosheet which maintains a dispersed state and has reduced electrical conductivity while having the excellent thermal conductivity by having aluminum oxide coated on the surface of graphene can be manufactured, and a nanocomposite material with excellent heat radiation properties can be manufactured by using the same.</p> |
