Abstract: The present invention belongs to the field of alkaline polymer electrolyte membranes, and relates to a comb-shaped structure polybenzimidazole anion exchange membrane with high conductivity and preparation method thereof. In the invention, firstly, polybenzimidazole is grafted with the non-cationic side chains to the max grafting rate to synthesize the de-protonated comb-shaped polybenzimidazole material, avoiding the N—H in benzimidazole forms ionic binding with cationic functional groups, which will reduce the reactivity and mobility of cationic groups; then react de-protonated comb-shaped polybenzimidazole with quaternization reagent to attach the pendent side chain with cationic functional groups, making it easy to aggregate to form ion clusters and hydrophilic/hydrophobic microphase separation. The anion exchange membrane prepared in this invention has excellent conductivity, mechanical properties and alkaline stability.

The present invention further provides a method of recovering protein by using the system. After the sugar liquid in the saccharification tank is stood, the protein floats at the upper part of the saccharification tank and the lower liquid is clear and transparent and thus the sugar liquid can be directly filtered. When the saccharification tank is discharged, the lower liquid is firstly discharged with the remaining liquid being bottoms containing protein. During a production process, enzymatic hydrolysis is performed for the sugar liquid containing protein before filtration to improve the filtration effect of the sugar liquid. Assisted by the plate and frame filter, protein can be recovered.
