Composite membrane substrate |
| abstract |
To provide a substrate for a composite membrane comprising a microporous polyolefin membrane the pores of which can be satisfactorily loaded with a hydrophilic resin compound and which has favorable permeability to an aqueous solution with a high water concentration and a comparatively high surface free energy, without hydrophilization pretreatment being carried out thereon.A substrate for a composite membrane comprising a microporous polyolefin membrane for carrying a hydrophilic resin compound within the pores of the microporous membrane wherein: the average pore diameter is 1 nm to 50 nm; the porosity is 50% to 78%; the membrane thickness is 1 µm to 12 µm; and, when a mixed solution of ethanol and water (volume ratio 1/2) is dripped onto a surface of the microporous polyolefin membrane which has not undergone hydrophilization treatment, the contact angle θ1 between the droplet and the surface is 0 to 90 degrees 1 second after the dripping, and the contact angle θ2 between the droplet and the surface is 0 to 70 degrees 10 minutes after the dripping, and the rate of change of the contact angle ((θ1 - θ2)/θ1 × 100) is 10 to 50%. |
