a Alignment of GO LCs with magnetic field. Top: experiment diagram of magnetic field-induced alignment. Bottom: texture of GO LCs aligned by magnetic field [7]. b Birefringence induced by electric field. Top: birefringence variation of 0.1 % GO dispersion under 10 kHz and various electric fields. Bottom: no birefringence change for 1.1 % GO dispersion with the same electric field [65]. c, d GO dispersion birefringence (Δn) as a function of electric field (c) and as a function of concentration (d) for GO with different sizes under electric of 20 V/mm [66]
