WebApr 12, 2024 · The basic principle of the top-down strategy is to exfoliate the as-synthesized layered COF bulk into COF nanosheets . This strategy mainly consists of mechanical exfoliation (ME) and liquid phase exfoliation (LPE) [40,41]. ME refers to a method of repeatedly sticking and peeling bulk COFs by transparent tape to obtain 2D thin films.
