    • Abstract


      Dimethylaminoethyl methacrylate maleate (DMAEMA–MA) polymerizable ionic liquid was synthesized from 2-(dimethylamino)ethyl methacrylate and maleic acid and characterized by ${}1$HNMR and FTIR. IC-P hydrogel was prepared by hydrothermal synthesis method using 2-acrylamide-2-methylpropane sulphonic acid and acrylamide as monomers, DMAEMA–MA as crosslinker and potassium peroxodisulphate as initiator. BIS-P hydrogel was prepared by using $N$,$N$'-methylene bisacrylamide (BIS) as non-ionic crosslinker, and the performances of BIS-P and IC-P hydrogels were compared. The results showed that IC-P hydrogel had a pore structure similar to BIS-P. When the dosage of DMAEMA–MA was 1.6% (based on the total mass of monomers), the swelling rate of the prepared IC$_{1.6}$ hydrogel in water can reach 235.97%, the conductivity was 58.8 ${\mu}$S cm$^{-1}$, and the derusting effect of Q235 low carbon steel with rust grade C could reach grade A. Moreover, DMAEMA–MA could improve the thermal stability of IC-P hydrogel.
