Direct observation of tunable thermal conductance at solid/porous crystalline solid interfaces induced by water adsorbates.

ABSTRACT: Improving interfacial thermal transport is crucial for heat dissipation in devices with interfaces, such as electronics, buildings, and solar panels. Here, we design a strategy by utilizing the water adsorption-desorption process in porous metal-organic frameworks (MOFs) to tune the interfacial heat transfer, which could benefit their potential in cooling or heat dissipation applications. We observe a changeable thermal conductance across the solid/porous MOF interfaces owing to the dense water channel formed by the adsorbed water molecules in MOFs. Our experimental and/or modeling results show that the interfacial thermal conductance of Au/Cu₃(BTC)₂, Au/Zr₆O₄(OH)₄(BDC)₆ and Au/MOF-505 heterointerfaces is increased up to 7.1
