    Abstract: A method of preparing a porous film comprises electrodepositing material from a mixture onto a substrate, the mixture comprising: (I) a source of metal, inorganic oxide, non-oxide semiconductor/conductor or organic polymer; (II) a solvent such as water; and (III) a structure-directing agent such as octaethylene glycol monododecyl ether to form an homogenous lyotropic liquid crystalline phase in the mixture. Electrodepositing the film from a lyotropic liquid phase in this manner provides a porous film having a substantially regular structure and substantially uniform pore size.

    Abstract translation: 制备多孔膜的方法包括将材料从混合物电沉积到基底上,所述混合物包含:(I)金属源,无机氧化物,非氧化物半导体/导体或有机聚合物,(II)溶剂如水 ; 和(III)结构导向剂如八甘醇单十二烷基醚,其量足以在混合物中形成均匀的溶致液晶相。 以这种方式从溶致液相中电沉积膜提供了具有基本上规则的结构和基本均匀的孔径的多孔膜。 沉积后,可以处理多孔膜以除去结构导向剂。 可以任选地对多孔膜进行进一步处理,例如离子物质的电化学或化学插入,有机,无机或有机金属物质的物理吸收,或有机,无机或有机金属物质的电沉积,溶液相沉积或气相沉积 。
