Abstract
There are disclosed a permselective membrane in a state of monomolecular polymer film obtained by subjecting a monomolecular film of a substance having at least one polymerizable group and a functional group to polymerization, and a process for producing this permselective membrane. This membrane is useful as a permselective membrane for gases, liquids, etc.
Claims16
A permselective membrane in a state of monomolecular film polymer or monomolecular built-up polymer, which comprises a polymer formed by subjecting a monomolecular film or a monomolecular built-up film of a substance containing at least one polymerizable group and a functional group to polymerization by means of a catalyst or radiation irradiation.
A process for producing a permselective membrane comprising a step of forming a monomolecular film or monomolecular built-up film of a substance containing at least one polymerizable group and a functional group on a hydrophilic substrate surface, a step of subjecting the polymerizable group to polymerization by means of a catalyst or radiation irradiation, and a step of removing a portion of the substrate by etching from the side on which neither monomolecular film nor monomolecular built-up film has been formed.
A process for producing a permselective membrane comprising a step of forming a monomolecular film or monomolecular built-up film of a substance containing at least one polymerizable group and a functional group on a hydrophilic substrate surface, a step of subjecting the polymerizable group to polymerization by means of a catalyst or radiation polymerization, a step of modifying the surface of the monomolecular film or the monomolecular built-up film by chemical treatment or physical treatment, and a step of removing a portion of the substrate by etching from the side on which neither monomolecular film nor monomolecular built-up film has been formed.
