چکیده
In this work, we report the synthesis and characteristics of cyclomatrix polyphosphazene membranes based on interfacial polymerization between 1,1-tris(4-hydroxyphenyl)ethane hexachlorocyclotriphosphazene top alumina or polyacrylonitrile supports. The potential alumina-supported thin film composite as organic solvent nanofiltration has been confirmed with a polystyrene-based molecular weight cutoff 347 ± 120 Da 503 220 in acetone toluene, respectively. Also, resulting TFC membrane showed methylene blue rejection (Mw = 319 g mol−1) 98.2 2.3%, 92 1.7%, 93 0.5% water, ethanol, acetone, Furthermore, prepared support via to validate preparation technique for polymeric supports facilitate industrial implementation. higher permeance lower than due presence pinholes selective layer Our results clearly show great membranes. However, polyacrylonitrile-supported membranes, method needs further investigation.

Nanopapers for organic solvent nanofiltration.
Would it not be nice to have an organic solvent nanofiltration membrane made from renewable resources that can be manufactured as simply as producing paper? Here the production of nanofiltration membranes made from nanocellulose by applying a papermaking process is demonstrated. Manufacture of the nanopapers was enabled by inducing flocculation of nanofibrils upon addition of trivalent ions.

A nanofiltration method has been developed in a microfluidic format for the continuous-flow pressure-driven purification of half-generation poly(amidoamine) (PAMAM) dendrimers, a family of macromolecules characterized by highly branching structures radiating from a central core, without additional solvents or buffers. An organic solvent resistant nanofiltration membrane, STARMEM 122, has been f...
