Selectively permeable material, method for producing selectively permeable membrane structure, selectively permeable membrane structure, and air conditioning system

A permselective material comprising a polymer having an organosiloxane skeleton and containing an ionic liquid additive,

• wherein when oxygen and nitrogen are passed through a membrane comprising the permselective material, the relation between the permeability coefficients [cm3·cm·sec−1·cm−2·cmHg−1] of oxygen and nitrogen at a temperature of 23±2° C. under a pressure difference of 1.05 atm to 1.20 atm through the membrane is expressed by Formula (1):

A method of making a permselective membrane structure comprising the steps of:

• filling openings of a reinforcement mesh with a mesh filler;
• reducing the volume of the mesh filler filled in the openings;
• forming a permselective membrane of a permselective material so as to cover exposed portions of the reinforcement mesh uncovered with the mesh filler and exposed portions of the mesh filler filled in the openings;
• and
• removing the mesh filler from the openings of reinforcement mesh after the formation of the permselective membrane;
• wherein the permselective membrane structure includes the reinforcement mesh and the permselective membrane stacked on the reinforcement mesh.

A method of making a permselective membrane structure comprising the steps of:

• filling openings of a reinforcement mesh with a mesh filler;
• forming an intermediate layer capable of bonding both the mesh filler and a permselective material on exposed portions of the mesh filler filled in the opening;
• reducing the volume of the mesh filler filled in the opening;
• forming a permselective membrane of a permselective material so as to cover exposed portions of the reinforcement mesh uncovered with the mesh filler and the intermediate layer;
• and
• removing the mesh filler and the intermediate layer from the openings of the reinforcement mesh after the formation of the permselective membrane;
• wherein the permselective membrane structure includes the reinforcement mesh and the permselective membrane stacked on the reinforcement mesh.
