The application area of existing gas separation membranes is limited by commercially available polymers for their preparation. One of the ways to improve the separation affectivity of existing membranes from glassy polymers is gas phase fluorination. It is very important to note that this method can be successfully used for...
The objective of this study is to present an overview of manufacturing techniques that can be used to produce solvent-free polymer membranes. The applicability of various methods is discussed. In particular, a new continuous technique by foam extrusion from the thermoplastic polymer is presented. Open-cell hollow fibers made of polyethersulfone...
This paper discusses microporous polyethylene films, which were formed in a process based on melt extrusion. Composite membranes were prepared by oxidative polymerization of conducting polymers (polyaniline, polypyrrole) or deposition from solution of polyelectrolyte polyacrylic acid in situ onto a polyethylene porous support. Multi-layer membranes consisting of different polymer layers...
A new method has been developed for determination and analysis of diffusion and distribution coefficients of salts in dialysis and RO membranes based on unsteady-state dialysis and steady-state RO experimental data. The method is based on a two-part model of heterogeneous RO membranes consisting of perfect or dense and imperfect...
