Abstract
A method for preparing a porous-polymer-modified metal carbon nanotube membrane includes: preparing an acidified carbon nanotube membrane; preparing a modification solution; heating the acidified carbon nanotube membrane in the modification solution and reacting to obtain a metal carbon nanotube membrane; conducting a polymerization reaction to obtain a crude polymer product; coating the metal carbon nanotube membrane with a polyethylene glycol diglycidyl ether (PEGDEG) solution; coating the metal carbon nanotube membrane with a porous polymer solution; and heating the metal carbon nanotube membrane to obtain the porous-polymer-modified metal carbon nanotube membrane. A porous-polymer-modified metal carbon nanotube membrane is prepared according to this method.
