TEMPERATURE-RESPONSIVE HOLLOW FIBER MEMBRANE, TEMPERATURE-RESPONSIVE HOLLOW FIBER MEMBRANE MODULE, AND FILTERING DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a temperature-responsive hollow fiber membrane high in cleaning effect thereof, and capable of suppressing the rise of the differential pressure of a membrane surface for a long time, a temperature-responsive hollow fiber membrane module, and a filtering device using the same.;SOLUTION: The temperature-responsive hollow fiber membrane 1 has a pore diameter adjustment material 3 formed by the graft-polymerization of N-isopropyl acrylamide on the outer surface side of a hollow fiber membrane 2 consisting of a polymer material. The pore diameter adjustment material is reversibly expanded/contracted at a predetermined temperature.;COPYRIGHT: (C)2007,JPO&INPIT
