Asymmetric geometry composites arranged between parallel aligned and interconnected graphene structures for highly efficient thermal rectification

Abstract

A novel framework of binary asymmetric geometry composites was arranged between parallelly aligned and interconnected, microcosmic, graphene structures. The greater number of efficient, heat transfer channels in interconnected graphene networks (one end) than in the parallelly aligned structures (another end) resulted in both ends of the thermal conductivity saltation. Therefore, this resulted in the adjustment of the thermal rectification of graphene composites to control the direction of heat flow.
