Preparation and applications of the epoxy resin-based polymer- stabilised cholesteric liquid crystal films with microcracks at the surface

Structural coloured epoxy resin patterns prepared using thermochromic epoxy liquid crystal mixtures

“…70 Without interlocking, the structural colour of a CLC mixture can cover the full visible range. 45 Based on this thermochromic behaviour, two CLCN gratings were prepared using one- (1D) and two-dimensional (2D) grating photomasks, Fig. 7a and b, respectively.…”

“…37 Recently, it was reported by our group that the CLCN patterns can be prepared using nematic epoxy liquid crystals with the addition of chiral dopants. 37,45 These patterns are potentially applied for decoration and anti-counterfeiting.…”
