Poly(urethane-imides) and Poly(ester-imides) as Promising Materials for Gas Separation and Pervaporation Membranes
This review focuses on the separation properties of membranes based on poly(urethane-imides)—modern products of the chemical modification of polyimides and polyurethanes. The membrane properties of poly(urethane-imides) are reviewed in terms of their chemical design. Membranes based on multiblock (segmented) polymers, polyimides crosslinked by polyurethanes, hybrid poly(urethane-imide) materials, and poly(urethane-imides) subjected to the selective destruction of urethane blocks are considered. The main directions of synthesis of membrane poly(urethane-imides) are described, and reactants and reaction conditions are presented. The transport and separation properties of poly(urethane-imide) membranes in separation, pervaporation, and ultrafiltration processes are addressed in detail. Applications of poly(urethane-imide) membranes are discussed. The review provides insight into the importance of poly(urethane-imide) gas separation and pervaporation membranes for separation processes.
期刊介绍:
The journal Membranes and Membrane Technologies publishes original research articles and reviews devoted to scientific research and technological advancements in the field of membranes and membrane technologies, including the following main topics:novel membrane materials and creation of highly efficient polymeric and inorganic membranes;hybrid membranes, nanocomposites, and nanostructured membranes;aqueous and nonaqueous filtration processes (micro-, ultra-, and nanofiltration; reverse osmosis);gas separation;electromembrane processes and fuel cells;membrane pervaporation and membrane distillation;membrane catalysis and membrane reactors;water desalination and wastewater treatment;hybrid membrane processes;membrane sensors;membrane extraction and membrane emulsification;mathematical simulation of porous structures and membrane separation processes;membrane characterization;membrane technologies in industry (energy, mineral extraction, pharmaceutics and medicine, chemistry and petroleum chemistry, food industry, and others);membranes and protection of environment (“green chemistry”).The journal has been published in Russian already for several years, English translations of the content used to be integrated in the journal Petroleum Chemistry. This journal is a split off with additional topics.
