Thermal Conductivity of Covalent Organic Frameworks as a Function of Their Pore Size

Covalent organic frameworks (COFs) are a relatively new class of organic nanostructured porous materials, formed by covalent bonds between light elements, with high surface area. The thermal conductivity values (k) for some COFs (COF-300, RIO-1, RIO-4, RIO-20) were measured using the modified transi...

Summary:Covalent organic frameworks (COFs) are a relatively new class of organic nanostructured porous materials, formed by covalent bonds between light elements, with high surface area. The thermal conductivity values (k) for some COFs (COF-300, RIO-1, RIO-4, RIO-20) were measured using the modified transient plane source (MTPS) technique. Values ranging from 0.038 to 0.048 W m–1 K–1 were measured depending on the COF pore structure and surface area. Thermal conductivities correlate linearly with the inverse of the cross-sectional area of the pores.
