The present invention relates to a composite semipermeable membrane including: a support membrane; and a separation functional layer provided on the support membrane, in which the separation functional layer includes a thin membrane, the thin membrane has a fold structure including a plurality of protrusions having a height of 10 nm or more, and in the fold structure, a ratio (T100/T25) is less than 0.95, where T25 is a thickness of the thin membrane in a region of 0% to 25% of the height of the protrusion and T100 is a thickness of the thin membrane in a region of 50% to 100% of the height of the protrusion.

Composite semipermeable membrane

According to the present invention, it is possible to obtain a separation membrane element which has an element configuration having high fresh water production performance and high removal performance, has an improved membrane surface linear velocity whereby fouling due to hardly-soluble salts (scales) or organic matters is less likely to occur on the membrane surface particularly in high recovery ratio operation, and is excellent in fresh water production performance and removal performance over a long period of time.

Separation membrane element and operation method therefor

An object of the present invention is to provide a separation membrane having high permeability and selective removability of divalent/monovalent ions. The separation membrane of the present invention includes a supporting membrane and a separation functional layer formed on the supporting membrane, in which the separation functional layer contains a polymerized product of a polyfunctional amine with a polyfunctional acid halide, the polyfunctional amine contains a polyfunctional aliphatic amine as a main component, the separation functional layer has a hollow protuberant structure, and the separation functional layer has a relative surface area of 1.1-10.0.

Separation membrane, separation membrane element, water purifier, and method for producing separation membrane

This composite semipermeable membrane is provided with: a porous supporting membrane that comprises a base and a porous supporting layer; and a separating function layer that is provided on the porous supporting layer. With respect to this composite semipermeable membrane, the standard deviation of pore radius of the separating function layer as determined by positron annihilation lifetime measurement is 0.025 nm or less.

Composite semipermeable membrane and method for producing composite semipermeable membrane

The present invention relates to a composite semipermeable membrane including a supporting membrane and a separation functional layer disposed on the supporting membrane, in which the separation functional layer comprises an aromatic polyamide, the aromatic polyamide has side chains and terminal groups, at least one of the side chains and terminal groups of the aromatic polyamide being an amino group, at least one of the side chains and terminal groups of the aromatic polyamide is a substituent having a structure represented by formula (1): &#x2014;NXY or formula (2): &#x2014;NXYZ, and in the aromatic polyamide, a content A of substituents having structures represented by formula (1) and formula (2) and a content B of amide groups satisfy 0.005&#x2264;A/B&#x2264;0.15.

A glass film laminate () for a touch panel includes a glass film (), a glass film (), a glass film (), and transparent adhesive layers (). The glass films (), () form both outermost layers. The glass film () has a transparent conductive layer () formed on each of both surfaces thereof. The glass films (), (), () each have a thickness of 200 &#x3bc;m or less. The glass film laminate () for a touch panel itself assumes a curved state without the application of an external force, in which a curved concave surface () and a curved convex surface () are formed. The curved concave surface () has formed therein a compressive stress, and the curved convex surface () has formed therein a tensile stress.
