Problems solved by technology

[0003] However, the traditional polyarylether polymer film has the following problems: (1) The polyarylether polymer without functionalization is hydrophobic, and its The prepared separation membrane is prone to membrane fouling, which leads to a decrease in the performance of the membrane and an increase in the separation cost; it is generally believed that after the membrane material is modified by hydrophilicity, it can reduce the adsorption of organic substances such as proteins by the membrane, improve the biocompatibility and Water Flux of Separation Membrane
(2) Separation membranes prepared from amorphous polyarylether polymers, such as polysulfone and polyethersulfone membranes, can only be used for a long time in water systems, but for organic solvent systems or organic solvents and water mixe
