Abstract:
For the first time, covalent organic frameworks (COFs) are integrated into the supramolecular nanofibrous membranes via thermally induced precursor crystallization (TIPC), preparing recyclable filters for air purification. Benefiting from their hierarchical porous structures and thermally reversible properties, the composite nanofibrous membranes exhibit high particulate matter (PM) filtration efficiency alongside excellent closed-loop recyclability.
