Title:
PRODUCTION METHOD FOR GAS SEPARATION COMPOSITE MEMBRANE, LIQUID COMPOSITION, GAS SEPARATION COMPOSITE MEMBRANE, GAS SEPARATION MODULE, GAS SEPARATION DEVICE, AND GAS SEPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/038285
Kind Code:
A1
Abstract:
Provided is production method for a gas separation composite membrane that has excellent gas separation capabilities, that has excellent durability and folding endurance, and that can be worked into a variety of shapes of modules. Also provided is a liquid composition that is ideal for the production method. Also provided is a gas separation composite membrane that has excellent gas separation capabilities, that has excellent durability and folding endurance, and that can be worked into a variety of shapes of modules. Also provided are a module, a device, and a gas separation method that use the gas separation composite membrane. According to the production method for a gas separation composite membrane, a mixed liquid that contains compounds (a) and (b) is applied to a porous support body so as to form a coating film thereon, and the coating film is cured so as to form a cross-linked polysiloxane compound layer. (a) A specific cross-linking polysiloxane compound that includes structural unit (a1), structural unit (a2), and structural unit (a3) or (a4). (b) A specific cross-linking polysiloxane compound that includes structural unit (b1), structural unit (b2), and structural unit (b3) or (b4). In the formulas, R1a-R1f and R2a-R2f indicate a specific group. * indicates a specific connecting part.
