Liquid crystals based on dispersions of two-dimensional (2D) materials have recently been developed for light modulation, exhibiting superior performances compared to conventional organic liquid in a variety prototypical applications, including coloration, solar-blind communications and blue-light fluoresce. Among the diverse family 2D crystals, vermiculite-based stand out with advantages low cost, ease mass production environmental sustainability, owing high natural abundance material. Here, we demonstrated magnetic-field tunable optics vermiculite prepared through facile ‘exchange redispersion’ method. By exploiting intrinsic ion-exchange capability clay minerals, observed significantly enhanced magneto-birefringence dispersion upon replacing native cations magnetic ions, manifesting doubled Cotton–Mouton coefficient, representing highest value among previous reports. Magnetization measurements reveal that there is remarkable anisotropy Fe ion-exchanged samples contrast isotropic magnetism pristine vermiculite, which accounts enhancement magneto-birefringence. Our findings demonstrate ion exchange can serve as simple effective strategy modulate physical chemical properties materials’ dispersions, thereby opening avenues broader more applications.
