Zusammenfassung: | The invention belongs to the technical field of fiber membranes. The invention provides a composite fiber membrane. The composite fiber membrane comprises a hydrophobic layer, a transfer layer and a hydrophilic layer, wherein the hydrophobic layer is made of polyvinylidene fluoride and/or polytetrafluoroethylene; the raw materials of the transfer layer comprise a component A and a component B in a weight ratio of 1:(9-11); the hydrophilic layer comprises a component C and a component B in a weight ratio of 1:(9-11); the component A is polyvinylpyrrolidone or polyethylene glycol; the component B is polyaniline, polyether sulfone, polylactic acid or cellulose acetate; and the component C is 2-methacryloyloxyethyl phosphorylcholine or poly[(2-methacryloyloxy) ethyl]dimethyl-[3-sulfopropyl]ammonium hydroxide. The invention also provides a preparation method and application of the composite fiber membrane. The composite fiber membrane disclosed by the invention has good one-way water transportation performance; an |
