Preparation method of a self-supporting oil-water separation hydrogel porous membrane |
| abstract |
The invention discloses a preparation method of a self-supporting oil-water separation hydrogel porous membrane: (1) synthesizing the first non-porous hydrogel and soaking it in the synthesis solution of the second hydrogel to swell Equilibrium; (2) Freeze the first hydrogel of the synthetic solution containing the second hydrogel, and initiate the polymerization of the second hydrogel; (3) After the polymerization is complete, melt the ice crystals to obtain a self-supporting porous hydrogel membranes for oil-water separation. The hydrogel porous membrane prepared by the invention has good mechanical properties, continuously adjustable pore diameter and porosity, and can be applied to different oil-water mixtures. |
