Abstract: front page image
(EN)An aromatic polyamide porous film that excels in thin-film forming capability and can easily express stable porous characteristics even after use at high temperature for a prolonged period of time. There is provided an aromatic polyamide porous film consisting of a porous film composed mainly of an aromatic polyamide, characterized in that on at least one major surface thereof, when the range of section area S μm2 is measured by means of an atomic force microscope, the section area at a depth of 10 nm from the top surface, S(10) μm2, and the section area at a depth of 20 nm from the top surface, S(20) μm2, simultaneously satisfy the relationships: 0.01≤S(10)/S≤0.3, and 5≤S(20)/S(10)≤20.
(FR)La présente invention concerne un film poreux de polyamide aromatique qui présente une excellente capacité à former des films minces et qui peut facilement produire des caractéristiques poreuses stables, même après utilisation à haute température pendant une période prolongée. La présente invention concerne un film poreux de polyamide aromatique qui comprend un film poreux composé principalement d'un polyamide aromatique, caractérisé en ce que sur au moins une surface principale de ce film, quand la plage de la superficie de la section S µm2 est mesurée au moyen d’un microscope à force atomique, la superficie de la section à une profondeur de 10 nm par rapport á la surface du dessus, S(10) µm2, et la superficie de la section à une profondeur de 20 nm par rapport á la surface du dessus, S(20) µm2, satisfont simultanément les relations : 0,01 ≤ S(10)/S ≤ 0,3 et 5 ≤ S(20)/S(10) ≤ 20.
(JA) 本発明は、薄膜化に優れ、高温で長期間使用しても安定した多孔質特性を容易に発現し得る芳香族ポリアミド多孔性フィルムを提供することを課題とし、芳香族ポリアミドを主成分とする多孔性フィルムであり、少なくとも一方の表面において、原子間力顕微鏡を用いてSμmの範囲を測定した時、表層から10nmの深さで切った断面積S(10)μmおよび表層から20nmの深さで切った断面積S(20)μmが下式を同時に充たすことを特徴とする芳香族ポリアミド多孔性フィルムとすることにより達成できる。 0.01≦S(10)/S≦0.3 5≦S(20)/S(10)≦20
