• Ionic-Liquid Control of Bottlebrush Block Copolymers

  2026-08-11

  Rodriguez, Mahanthappa, and Lodge examine how coil-bottlebrush diblock copolymers assemble in a systematic series of alkylimidazolium ionic liquids. Their central result is that, at a coil volume fraction near 0.38, lyotropic morphology depends surprisingly weakly on ionic-liquid alkyl-chain length despite substantial changes in solvent selectivity.
