Nanocomposite membranes for organic solvent nanofiltration: Recent advances, challenges, and prospects

Functionalized graphene oxide-based lamellar membranes for organic solvent nanofiltration applications

“… 13 Inorganic membranes have superior stability in organic solvents; but the large scale production of such membranes is complicated and more costly than polymeric membranes. 14 Therefore, it is challenging task to develop novel OSN membranes with superior stability in various organic solvents along with high separation performance and permeance simultaneously.…”

Performance of a membrane fabricated from high-density polyethylene waste for dye separation in water

“…17 In particular, the membrane process has been widely applied in the dye ltration process, both through the microltration (MF) process to reverse osmosis (RO). [18][19][20][21][22] Nanoltration membranes (NFs) are more commonly used for dye ltration due to their smaller pore size than the MF process. Membranes can be fabricated with a variety of materials from natural to synthesized, such as cellulose acetate, polyvinylidene uoride (PVDf), and polyethersulfone (PES).…”

Alkyl-Engineered Hydrophobic Channels in Covalent Organic Frameworks toward Fast Organic Solvent Nanofiltration

“…However, COFs with different pore sizes but the same skeleton are preferred to systematically explore the factors affecting membrane selectivity, which is important for optimizing novel COF-based membranes. Such COFs can be achieved by introducing functional groups of different sizes on the pore wall of COFs. − The introduction of functional groups on the pore wall can create completely different pore environments, thereby altering the interaction between solvents and COFs and affecting the solvent transport behavior. However, the introduction of functional groups either increases the difficulty of synthesis by the de novo synthesis from functionalized building units or destroys the structure of COF membranes by post-functionalization.…”
