Hydrophilic porous membrane, method for production thereof, and plasma separator using said membrane |
摘要 |
A hydrophilic porous membrane has graft chains of a hydrophilic monomer formed on the surface of a hydrophobic porous membrane so as to impart to the surface perfect hydrophilicity such that the produced membrane, when wetted, exhibits a swelling ratio of not more than 1% and a bubble point in the range of 0.5 to 8 kg/cm2. The hydrophilic porous membrane is produced by irradiating the hydrophobic porous membrane with plasma, feeding the hydrophilic monomer in a gaseous state, and allowing the hydrophilic monomer to be graft polymerized on the surface of the porous membrane. A plasma separator is obtained by using the aforementioned hydrophilic porous membrane as a plasma separation membrane.
