POLYMER COMPOSITE PRODUCING INSULATING MATERIAL OF A HIGH VOLTAGE DIRECT CURRENT CABLE FOR POWER TRANSMISSION AND METHOD THEREOF

摘要

PURPOSE: A polymer composite is provided to remove a space charge generated in an insulating material of a high voltage direct current cable for power transmission by comprising a partially reduced material of a graphene oxide. CONSTITUTION: A polymer composite comprises a graphene oxide partially reduced by 80-0.01%. The comprised amount of the partially reduced material of graphene oxide is 0.01-50 weight%. The size of the partially reduced material of graphene oxide is 15 um or less. A manufacturing method of the partially reduced material of graphene oxide is 15 um or less. A manufacturing method of the polymer composite comprises a step(S20) of manufacturing the partially reduced material of graphene oxide by partially reducing graphene oxide; a step(S30) of manufacturing a polymer composite comprising the partially reduced material.
