Abstract

Controlling and tuning thermal conductivities of composites, including changing the direction of heat flux and thermal energy distribution, possesses significantly meaningful potential in many applications such as heat cloak, heat invisibility, heat protection and so on. In this paper, a novel design of composite metamaterial with periodic lattice structure, consisting of metal lattice layer (copper) and stretchable polymer matrix (Ecoflex), owns the ability to tune the anisotropic thermal conductivity through external strains. The parameters (such as geometric arrangement of metal lattice, loading strains), which can effectively influence the thermal properties of this metamaterial, have been investigated through finite element method considering large deformation. This new design may be helpful for designing and controlling heat flow and temperature distribution in the applications.
