OXYGEN ENRICHMENT MEMBRANE AND METHOD FOR PRODUCING SAME

摘要

The present invention relates to an oxygen enrichment membrane that is capable of ensuring an oxygen separation performance and physical membrane properties (mechanical strength, deposition performance, etc.) at the same time and capable of obtaining high-concentration oxygen in an industrial manner. The present invention has a hydrocarbon radical-containing polysiloxane mesh structure in which tetraalkoxysilane and hydrocarbon radical-containing dialkoxysilane react with each other as a main material. The tetraalkoxysilane is tetramethoxysilane or tetraethoxysilane (this being A) and the hydrocarbon radical-containing dialkoxysilane is dimethyldimethoxysilane or diethyldiethoxysilane (this being B). A mixing ratio between A and B (A/B) is set to a molar ratio of 1/9 to 9/1.
