There is provided a laminated film that is usable as a filter and has the strength high enough to withstand the pressure applied in filtration without breaking and a good filtration rate. A laminated film comprising a thin film and a support film stacked on top of each other, the thin film having a thickness of 1 nm to 1 µm and including a first pore portion having one or more pores, the support film having a thickness of 1 to 100 µm and including a second pore portion having one or more pores. The pores of the thin film has an average aspect ratio of not more than 2, the thin film has an opening ratio of not more than 80%, and the first pore portion in the thin film is disposed so as to meet a predetermined relationship with the second pore portion in the support film.

摘要:
To provide a surface treatment liquid capable of making a base material including polyorganosiloxane on at least a part of a surface thereof hydrophilic stably over a long period of time, and provide a surface treatment method using the surface treatment liquid. In a surface treatment liquid including (A) resin and a (B) solvent, as the (A) resin, resin having a functional group I that is a hydroxyl group and/or a cyano group is used, and a functional group II that is a hydrophilic group other than the functional group I, and a ratio of a structural unit having an anionic group to total structural units of the (A) resin is 5 mol% or less, or resin including a cationic group including an anion moiety and a cation moiety that can be bonded to the (A) resin is used.
摘要:
To provide a surface treatment method capable of successfully making a treatment target including polyimide on a surface thereof hydrophilic or hydrophobic with a safe operation; a two-liquid type surface treatment liquid that can be suitably used for the surface treatment method; and a surface-treated polyimide product that can be obtained by the above-described surface treatment method. A first resin having a primary amino group and/or a hydroxyl group, and a secondary amino group is bonded to a surface of a treatment target including polyimide on a surface thereof, and then a second resin having a (meth)acryloyl group and/or a carbamoyl group, a hydrophilic group and/or a hydrophobic group is bonded to the first resin.

The composite layer material (10) is made up of at least two laminated layers. One of outermost layers is a support film (2) that is removable from another layer and has a self-supporting property.
摘要:
To provide a membrane filter including a thin film having a nanometer order thickness as a base, which is easy to increase the size and also has enough strength for use as a filter. The membrane filter is formed by laminating a thin film having a thickness of 1 to 1,000 nm with a support film which is a porous film having a thickness of 1 to 1,000 µm, which is made of a photosensitive composition or a cured product of the photosensitive composition, and has a plurality of hole portions penetrating in the thickness direction.
