Title:
METHOD FOR PRODUCING FUNCTIONAL MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2007/094279
Kind Code:
A1
Abstract:
Disclosed is a method for producing a functional membrane which has a structure wherein fine pores of a porous base are filled with a functional polymer. This method is improved in productivity and enables to produce a functional membrane having improved stability in performance. Specifically disclosed is a method for producing a functional membrane wherein fine pores of a porous base are filled with a functional polymer, which method is characterized in that the porous base is treated with a suspension of a surface active agent before filling a functional polymer solution or a precursor solution thereof into the fine pores of the porous base, and then the functional polymer solution or the precursor solution thereof is filled into the fine pores after a drying step following the treatment.
