Properties and mechanism of a poly(ionic liquid) inhibitor contained bi‐functional groups for bentonite hydration

Present polymer inhibitors depend on a major inhibitory group to restrain bentonite hydration, and monomer design is concerned to improve the inhibition and stability through complex copolymerization. Conveniently, a homopolymer (PIL‐NH 2 ) that contained primary amine and cationic imidazolium as bi‐functional groups was proposed, aiming to provide two synergistic inhibitory modes. Comprehensive methods were conducted to characterize the...
