INORGANIC FIBER REINFORCED ORGANIC-INORGANIC HYBRID ION EXCHANGE MEMBRANE WITH HIGH DIMENSIONAL STABILITY AND HIGH THERMAL RESISTANCE AND METHOD FOR MANUFACTURING THE SAME

摘要

The present invention relates to an inorganic fiber reinforced organic-inorganic hybrid ion exchange membrane with a high dimensional stability and a high thermal resistance, and to a manufacturing method thereof. More specifically, the inorganic fiber reinforced organic-inorganic hybrid ion exchange membrane has an excellent oxidative stability such that the ion exchange membrane has a high thermal resistance, and has a high dimensional stability, thereby being usable in various temperature ranges. The ion exchange membrane according to the present invention is made of a siloxane bond which is stable in oxidation or made of a siloxane bond and saturated hydrocarbon, thereby having an excellent oxidative stability and thermal resistance. Also, the complex ion exchange membrane is realized by applying inorganic fiber having a low thermal expansion coefficient, thereby significantly improving a dimensional stability. Thus, the ion exchange membrane of the present invention can be used in various temperature ranges.
