Effect of ionic liquids on microstructures of micellar aggregates formed by PEO-PPO-PEO block copolymer in aqueous solution

- Aqueous mixed systems of Pluronics® (F127) with various pyridinium based ILs were studied.
- Size and shape for micelles of F127 in aqueous solutions of ILs were measured by SANS and DLS.
- The interactions between PEO/PPO with ILs were checked by 1H NMR and viscosity.
- Upon addition of ILs, an enhancement in CMC and reduction in micellar size of F127 were found.
- Effect of alkyl chain length, head group, anions and concentration of ILs has been discussed.
