Metal organic frameworks (MOFs) are group of porous materials synthesized by self-assembly of metal ions and organic ligands. They attract researchers’ attention because of high storage and separation ability against gas molecules. The thermal conductivity (κ) of MOF is an important property as the adsorption/desorption of gas molecules are exothermic/endothermic process. However, the evaluation of MOF κ is still lacking due to technical difficulties.
In this work, oriented MOF film was synthesized on metal wire, and its anisotropic κ was measured by bidirectional 3ω method. Also, its dependence on humidity is clarified.
