Abstract:In the field of emulsion separation, the application of porous hydrophilic sponge materials is of paramount importance; however, the conventional preparation process of hydrophilic poly(vinyl formal) (PVF) restricts the simultaneous enhancement of separation efficiency and water flux. In this work, by introducing two poly(vinyl alcohol) (PVA) and aldehyde feedstocks with different molecular weights and functional group contents into the reaction system, the differences in the mobility and reactivity of the fee… Show more
