Thermal Management: Conductivity of 2D Covalent Organic Frameworks with Nanopores
Managing temperatures is essential for the lifetime and performance of many materials and their devices. Two main applications include electronic devices and spacecraft. Covalent organic frameworks (COFs) are crystalline porous polymers, with tunable properties such as pore size and (thermal) conductivity. The thermal conductivity of benzobisoxazole (BBO)-linked two-dimensional, nanoporous COFs were studied in a recent paper, where calculations supported the experimental findings.
The 2D BBO-COFs showed high thermal conductivity, irrespective of their pore size, which suggest they would be useful ultralow-k materials with excellent thermal management properties.
