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

摘要

A permselective material has a polymer having an organosiloxane skeleton and containing a dispersed solid additive. When oxygen and nitrogen are passed through a membrane having 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): 0.94 ≤ P ⁡ ( O 2 ) P ⁡ ( N 2 ) < 1 ( 1 ) where P(O2) denotes the permeability coefficient of oxygen, while P(N2) denotes the permeability coefficient of nitrogen.
