Title:
多孔質支持体上にポリマー薄膜を調製する方法
Document Type and Number:
Japanese Patent JP6391566
Kind Code:
B2
Abstract:
Methods for preparing a polymer membrane on a porous support may include providing a porous support having an outer wall, a first end, a second end, and porous channel surfaces that define a plurality of channels through the porous support from the first end to the second end. The plurality of channels includes membrane channels. The channel surfaces that define the membrane channels are membrane-channel surfaces. The polymer membrane may be coated onto the porous support by first establishing a pressure differential between the outer wall and the plurality of channels. Then, a pre-polymer solution may be applied to the membrane-channel surfaces and, optionally, the first and second ends, by slip coating or emulsion coating while the pressure differential is maintained. This results in formation of a pre-polymer layer on at least the membrane-channel surfaces. Then, the pre-polymer layer may be cured to form the polymer membrane.
