【摘要】 研究了不同添加剂对乙基纤维素富氧膜性能的影响。结果表明,低分子向列液晶正庚基联苯腈（7CB）、低分子胆甾液晶油烯基胆甾醇碳酸脂（COC）以及过渡金属化合物二亚水杨基邻笨二胺钴[Co（Salphen）]的添加,皆可以较大程度地改进乙基纤维素高分子富氧膜的性能。过渡金属盐醋酸钴[Co（Ac）₂]仅能提高乙基纤维素富氧膜对富氧空气的透过性,而杂环化合物吡啶（PY）只能提高乙基纤维素富氧膜的氧氮分离性而在某种程度上却降低了对富氧空气的透过性。更多还原

【Abstract】 The purpose of this article was to investigate the influences of a sreies of additives on the pcrfor mances of ethylcellulose oxygen-enriched membranes so as to choose the approriate additive to improve the performances of ethylcellulose oxygen-enriched membrane. The results show that different additive makes different effects on the performances of ethylcellulose oxygen-enriched membranes.更多还原
