Abstract:

This paper reviewed the influences of preparation methods on the porous structure and properties of polyvinyl alcohol (PVA)?based porous composites, including the emulsion template method, supercritical carbon dioxide method, electrostatic spinning method, freeze-drying method, pore-forming method and phase separation method. The applications of this type of porous composites in the adsorption field were presented in detail. Their relevant research and recent progress in the fields of oil/water separation, inorganic salts, and dye adsorption were described. The development trend in the functionalization of the porous composites through crosslinking modification was prospected.

Key words: polyvinyl alcohol, porous composite, preparation method, oil/water separation, adsorption
