Cyclodextrin-based supramolecular polyrotaxanes are for the first time used as soft nanoparticle additives for the selective layer of composite membranes. They exhibit outstanding gas transport characteristics at low additive percentages, due to the dynamic nature of the PDMS side chains.

Coating Method

Composite membranes comprised of a thin poly (N,N-dimethylaminoethyl methacrylate) layer and a microporous polysulfone substrate were prepared by coating method. The effects of parameters involved in the membrane preparation procedure on the permselectivity of the resulting membrane were investigated by a factorial design. The permeability of the membrane to N2, CH4 and CO2 was tested and the membrane showed a high permselectivity to CO2.

A «green» method of obtaining gas separation composite membranes from cellulose solutions and its mixtures with chitosan in orthophosphoric acid is proposed for industrial use, and differs from the viscose method of producing cellophane and other known methods for producing cellulose gas separation membranes without gaseous emissions and wastewater. It is shown that new composite cellulose membranes on a viscose fabric substrate are characterized by high productivity and selectivity for O2/ N2 pairs, comparable to the values obtained for known membranes made of synthetic polymers, as well as increased mechanical strength. The developed composite membranes demonstrate an inverse selectivity for the CH4/CO2 pair, which is not typical for gas separation membranes described in the literature with cellulose-based selective layers.
