摘要

提出了一种采用低温离子等离子体预处理纤维体系制备阳离子交换复合非均相膜的新方法。该膜是在聚合物复合材料的表面和新酚醛纤维体系结构中，通过合成和硬化强酸性硫离子交换剂，通过缩聚填充得到的。研究了低温离子等离子体预处理对多相阳离子交换复合材料Polykon的亲水性、毛细性和结构变化的影响。

Low-Temperature Ion-Plasma Pretreatment of Fibrous Systems during Preparation of Composite Heterogeneous Membranes

An original method of obtaining cation exchange composite heterogeneous membranes involving the low-temperature ion-plasma pretreatment of fibrous systems is proposed. The membranes are obtained by the polycondensation filling of polymer composites via the synthesis and hardening of a strongly acidic sulfo cation exchanger on the surface and in the structure of a novolac phenol-formaldehyde fibrous system. The effect of low-temperature ion-plasma pretreatment on a change in the hydrophilicity, capillarity, and structure of heterogeneous cation exchange composite materials Polykon is investigated.

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.
