These
disordered textures over a graphene sheet display similarities to
the presence of degenerated planar alignment.20,21 The overall
perceptible chiral nematic (N*LC) textures in the graphene cells
appear to be very similar to those in the ITO–ITO cell without PI
alignment layers, but interaction between graphene and the LC
molecules has been discussed in previous studies12 where these
rod-like LC molecules tend to align with the honey-comb lattice
