| 简介 |
The invention relates to novel organic/inorganic hybrid membranes which have the following composition : a polymer acid containing -SO3H-, -PO3H2-, -COOH- or B(OH)2 groups; a polymer base (optional), which contains primary, secondary or tertiary amino groups, pyridine groups, imidazole, benzimidazole, triazole, benzotriazole-pyrazole or benzpyrazole groups, either in the side chain or the main chain; an additional polymer base (optional) containing the aforementioned base groups; an elemental oxide, or metal oxide or metal hydroxide, which has been obtained by the hydrolysis and/or sol-gel reaction of one elemental organic and/or organometallic compound during the membrane forming process and/or by a re-treatment of the membrane in aqueous acidic, alkaline or neutral electrolytes. The invention also relates to methods for producing said membranes and to the various uses for membranes of this type. |
