Conductive hollow fiber membrane and preparation method thereof and membrane assembly

A preparation method of a conductive hollow fiber membrane, comprising following steps:

• Step 1:
• adding a functional monomer into a solvent, mixing to obtain a functional monomer solution, adding a polymerizable vinylimidazolium-based ionic liquid into the functional monomer solution, and stirring uniformly under heating conditions to obtain a modified solution;
• Step 2:
• immersing a lining support layer into the modified solution, incubating at room temperature, then transferring the lining support layer to a weak acid buffer solution for in-situ polymerization, and after completion of the reaction, washing and drying to obtain a conductive lining support layer;
• Step 3:
• performing spinning on the conductive lining support layer, subjecting it to phase inversion in a coagulation bath to obtain a membrane filament, immersing the membrane filament in pure water and glycerol in sequence, and drying to obtain a conductive hollow fiber membrane with a lining structure.
