Gas-responsive intelligent super-amphiphobic oil-water separation membrane material as well as preparation method and application thereof

The invention discloses a gas-responsive intelligent super-amphiphobic oil-water separation membrane material as well as a preparation method and application thereof. The preparation method comprises the following steps: firstly, preparing hydrophilic pi-conjugated polymer nanoparticles through a silicon dioxide nanoparticle template method; then, the negatively charged polyacrylic polyelectrolyte and the positively charged hydrophilic pi-conjugated polymer nanoparticles are deposited on a base material of a net structure or a porous structure through a spraying or layer-by-layer self-assembly method, and a porous nano-structure coating is obtained; the obtained gas-responsive intelligent super-amphiphobic oil-water separation membrane material can realize intelligent conversion from oil adhesion resistant super-amphiphobic to underwater super-oleophobic (super-hydrophilic) under gas stimulus responsiveness, has the advantages of rapid gas response, oil pollution resistance and strong self-cleaning ability, r
