摘要

介绍了以聚偏氟乙烯和磺化交联聚苯乙烯为原料，在轨道蚀刻膜上合成质子导电材料的方法。用苯乙烯/二乙烯基苯共聚，再用氯磺酸磺化聚苯乙烯，在原始或经γ辐照的轨迹蚀刻膜的孔中填充。用扫描电子显微镜和ATR红外光谱对所得膜进行了研究。测定了膜离子电导率、氢气渗透性、离子交换容量和吸水率。30°C时离子电导率达到51.7 mS/cm，几乎是Nafion®212膜的3倍;然而，所得材料的透气性也同时增加。

Pore Filled Ion-Conducting Materials Based on Track-Etched Membranes and Sulfonated Polystyrene

Synthesis of proton-conducting materials based on track-etched membranes from polyvinylidene fluoride and sulfonated cross-linked polystyrene is described. The synthesis has been carried out by filling the pores of the original or gamma-irradiated track-etched membrane by copolymerization of styrene/divinylbenzene followed by sulfonation of polystyrene with chlorosulfonic acid. The resulting membranes have been studied by scanning electron microscopy and ATR IR spectroscopy. Membrane ionic conductivity, hydrogen gas permeability, ion-exchange capacity, and water absorption were measured. The ionic conductivity at 30°C reaches 51.7 mS/cm, which is almost three times higher than for Nafion®212 membranes; however, the gas permeability of the obtained materials also increases simultaneously.

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.
