worldwide challenge of stabilized oil-in-water emulsion separation,
a PAM-PDVB decorated nylon membrane is fabricated via a facile solvothermal
route in our group. The main composition is PAM, while the PDVB plays
a role as cross-linker in order to improve the interaction between
the polymer and the substrate. By the combination of the superhydrophilic
and underwater superoleophobic wettability of the PAM polymer with
the micropore size of the substrate, the as-prepared material is able
to achieve the separation of various stabilized oil-in-water emulsions
including cationic type, nonionic type, and anionic type. Compared
with previous works, the emulsions used in this case are more stable
and can stay for several days. Besides, the solvothermal method is
facile, cost saving, and relatively environmentally friendly in this
experiment. Moreover, the PAM-PDVB modified membrane exhibits excellent
pH stability, recyclability, and high separation efficiency (above
99%), which can be scaled up and used in the practical industrial
field.
