| titleOfInvention | Preparation method of self-supporting through-type polyelectrolyte ordered porous membrane |
| abstract | The invention discloses a preparation method of a self-supporting through-type polyelectrolyte ordered porous membrane. The preparation method comprises the steps of: (1) dissolving a styrene copolymer into a solvent to prepare a uniform polymer solution, and preparing an ordered porous base membrane in an environment that the relative humidity is 60-95 percent; (2) ensuring that the surface of the base membrane has electric charge to prepare a charged ordered porous base membrane; (3) immersing the charged ordered porous base membrane into a polyanion solution or a polycation solution with specific hydrophobicity or responsibility to self-assemble layer by layer to obtain a polyelectrolyte thick membrane; and (4) soaking the polyelectrolyte ordered porous membrane into a release agent to oscillate and clean, and removing the ordered porous base membrane serving as a template to obtain the self-supporting through-type polyelectrolyte ordered porous membrane. Not relying on technologies of preparing porous materials such as the existing photoetching and electron beam lithography, the preparation method is simple in operation process, mild in process condition and low in cost, and can be used for obtaining the through-type polyelectrolyte ordered porous membrane with self-supporting performance. |
