Method for preparing through-hole polymer porous aquagel by using graphene oxide (GO)

The invention belongs to the technical field of materials, and particularly relates to a method for preparing a through-hole polymer porous aquagel by using graphene oxide (GO). The method mainly comprises the following steps: carrying out surface modification on hydrophilic GO by using an oleophylic modifier, wherein the modified GO is used as a stabilizer of a Pickering emulsion; and adding a monomer, a crosslinking agent, an initiator and a pore-forming agent, emulsifying to obtain an oil-in-water high-inner-phase emulsion, and carrying out continuous phase polymerization on the high-inner-phase emulsion to obtain the through-hole-structure polymer porous aquagel. The method has the advantages of simple preparation process and lower cost. The prepared through-hole polymer porous aquagel has the advantages of controllable pore structure, large pore size (5-200 mu m), large interconnection size (2-70 mu m), favorable permeability, favorable swelling capacity and favorable adsorbability.
