Rapid fabrication of fluorinated covalent organic polymer membranes for organic solvent nanofiltration

Bottom-up synthesis of two-dimensional carbon with vertically aligned ordered micropores for ultrafast nanofiltration

“…The nanofiltration performance of the o-2DZTC membrane was compared with that of other nanofiltration membranes reported in the literature (Fig. 4F) (29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47). The o-2DZTC membrane simultaneously exhibited very high methanol permeance and precise molecular separation with an MWCO of 344 g mol −1 , surpassing the upper bound of previously reported polymer-, metal organic framework-, and covalent organic framework-based membranes.…”

Pyrene-based covalent organic polymers with nano carbonaceous composites for efficient supercapacitive energy storage

“…[1][2][3][4][5][6] They are typically made up of light elements such as carbon, nitrogen, and oxygen, and can have diverse chemical structures, allowing for a wide range of properties and potential applications. [7][8][9][10][11][12] In recent years, there has been a growing amount of attention towards COPs because of their unique properties, including high surface area, tunable porosity, and chemical stability. [13][14][15][16][17][18][19][20] COPs can also be synthesized in a variety of ways, including through the polymerization of small molecules or through selfassembly of pre-formed building blocks.…”

Electropolymerized thin films with a microporous architecture enabling molecular sieving in harsh organic solvents under high temperature

“…The development of a new class of membrane materials is an important pathway to address the limitations of conventional membranes under industrial conditions. To this end, great efforts have been inspired for the integration of typical porous materials, such as zeolites, 18,19 covalent organic frameworks (COFs), [20][21][22][23] metal-organic frameworks (MOFs), 24,25 polymers of intrinsic microporosity (PIMs), 26,27 monolayer graphene, [28][29][30] and MoS 2 (ref. 31 and 32) into membranes.…”
