Rheological Tunable Magnetic Fluids with Long‐Term Stability (Small 8/2023)

Rheological Tunable Magnetic Fluids In article number 2204609, Hong Yang, Quan Li, and co-workers design a magnetic fluid by using oleic acid coated Fe3O4 nanoparticles as the magnetic particles, and the amphiphilic penta block copolymer-based aqueous solution as the carrier fluid. This magnetic fluid possesses outstanding long-term stability and reversible rheological changes between the low-viscosity flow state and the three-dimensional gel structure.
