摘　　要：研究了经逆向电解法剥离制得的铝阳极氧化多孔膜层在０．０１ｍｏｌ／ＬＫＣｌ溶液中的离子导电性。结果表明，多孔膜的离子导电性与膜的孔径大小有关。未经封孔的多孔膜对电解质在膜内迁移无阻碍作用；多孔膜经高温沸水或常温封孔剂封孔后，其离子导电性急剧减小，且经常温封孔后多孔膜的离子导电性在一定的时间内随膜的老化时间延长而减小。The ion electrical conductivity of anodized aluminum porous film, which was peeled off by reverse electrolysis from aluminum substrate, was investigated. The results were that, the ion electrical conductivity in 0.01 mol/L KCl of porous film was related to the diameter of film pore. The unsealed film didn't block the transport of electrelyte, but ion electrical conductivity was dropped sharply when the porous film was sealed by boiling water or cold sealing solutions. For the porous film sealed by cold sealant, the ion electrical conductivity would decrease with the increasing in aging time of film. The relationship betwen the admittance of sealed film in electrolyte solution and the weight loss of film in acidic solution was discussed.
