Abstract

A composite layer material including at least two laminated layers. One of outermost layers is a support film that is removable from another layer and has a self-supporting property.

First claim

1 . A composite layer material comprising at least two layers which are laminated,
wherein one of the outermost layers of the at least two layers is a support film that (i) is removable from another layer of the at least two layers; and (ii) has a self-supporting property.

2 . The composite layer material as set forth in claim 1 , wherein a thickness of the support film is 1 μm or more and 100 μm or less.

3 . The composite layer material as set forth in claim 1 , wherein the support film is made of a material that is to be dissolved in a liquid.

4 . The composite layer material as set forth in claim 3 , wherein the liquid is water or an aqueous solution.

5 . The composite layer material as set forth in claim 3 , wherein the liquid is an organic solvent.

6 . The composite layer material as set forth in claim 1 , wherein the another layer has a thickness of 10 nm or more and 1 μm or less.

7 . The composite layer material as set forth in claim 1 , wherein said composite layer material is made up of three or more layers which are laminated.

8 . The composite layer material as set forth in claim 1 , wherein:
at least one layer other than the one of outermost layers is a layer having a separating function to separate a certain substance from a mixture containing the certain substance.

9 . The composite layer material as set forth in claim 1 , wherein:
at least one layer other than the one of outermost layers is made of a material which contains at least one selected from the group consisting of (i) an organic compound having an epoxy group and (ii) an organic compound having an amino group.

10 . The composite layer material as set forth in claim 9 , wherein:
at least one layer other than the one of outermost layers is made of a material containing PCGF ((o-cresyl glycidyl ether)-formaldehyde copolymer) and PEI (polyethyleneimine); and a ratio between the PCGF and the PEI is in a range between 10:90 and 90:10, in terms of weight ratio.

11 . The composite layer material as set forth in claim 1 , wherein:
at least one layer other than the one of outermost layers is made of a material that contains (i) an organic compound having an epoxy group and (ii) a photo-acid-generating agent.

12 . The composite layer material as set forth in claim 1 , wherein:
at least one layer other than the one of outermost layers is made of a material containing a metal alkoxide.

13 . A method for manufacturing a membrane, said method comprising the steps of:
(a) forming at least one membrane on a support film that has a self-supporting property; and (b) removing the support film after the step (a).

14 . The method as set forth in claim 13 , wherein a thickness of the support film is 1 μm or more and 100 μm or less.

15 . The method as set forth in claim 13 , wherein:
the support film is made of a material that is to be dissolved in a liquid; and in the step (b), the support film is dissolved with the liquid.

16 . The method as set forth in claim 15 , wherein the liquid is water or an aqueous solution.

17 . The method as set forth in claim 15 , wherein the liquid is an organic solvent.

18 . The method as set forth in claim 13 , wherein each of the at least one membrane formed in the step (a) has a thickness of 10 nm or more and 1 μm or less.

19 . The method as set forth in claim 13 , wherein at least one membrane formed in the step (a) is a membrane having a separating function to separate a certain substance from a mixture containing the certain substance.

20 . The method as set forth in claim 13 , wherein:
at least one membrane formed in the step (a) is made of a material which contains at least one selected from the group consisting of (i) an organic compound having an epoxy group and (ii) an organic compound having an amino group.

21 . The method as set forth in claim 20 , wherein:
at least one membrane formed in the step (a) is made of a material containing PCGF ((o-cresyl glycidyl ether)-formaldehyde copolymer) and PEI (polyethyleneimine); and a ratio between the PCGF and the PEI is between 10:90 and 90:10, in terms of weight ratio.

22 . A method for manufacturing a layered body by laminating a support on an outermost membrane of at least one membrane manufactured with a method recited in claim 13 , said method comprising the step of:
(c) laminating the support on the outermost membrane after the step (a).

23 . The method as set forth in claim 22 , wherein:
in the step (c), the support is laminated, while the support film is removed in the step (b), on an outermost membrane that is different from a membrane on which the support film is provided.

24 . The method as set forth in claim 13 , wherein:
at least one membrane formed in the step (a) is made of a material that contains (i) an organic compound having an epoxy group and (ii) a photo-acid-generating agent.

25 . The method as set forth in claim 13 , wherein:
at least one membrane formed in the step (a) is made of a material containing a metal alkoxide.
