| titleOfInvention | Polyether sulfone microporous membrane and its manufacture |
| abstract | PURPOSE:To manufacture a microporous membrane having excellent liquid permeability and a bacterium collecting property by coating uniformly an original liquid consisting of polyether sulfone, N-methyl-2-pyrrolidone, and monohydric alcohol in a specified ratio on a supporting body, and dipping in an aq. solidifying bath under specified conditions. CONSTITUTION:A film-forming original liquid consisting of 10-35wt% polyether sulfone, 50-85wt% N-methyl-2-pyrrolidone, and 5-15wt% mono- or polyhydric alcohol is uniformly coated on a supporting body (glass plate, etc.). The coated body is then dipped in an aq. solidifying bath at a dipping speed of 0.5-5m/min and at an incident angle of 30-50 deg.. In this way, a microporous membrane, having micropores of 0.05-10mu mean pore diameter, 50-85% void ratio, 2-900ml/ cm<2>.min/-52cm Hg at 25 deg.C demineralized water permeating rate, and <=10 pore diameter ratio of the front to the rear surface, is obtained. The membrane possesses excellent resistance to chemicals and heat and physical strength. |
