Abstract

We investigate the fabrication of 'deformation-free' polymer/cholesteric liquid crystal (PChLC) nanocomposites by controlling the degree of phase separation in a precursor mixture containing mesogenic monomer and low molecular-weight LC molecules. Scanning electron microscopy investigations reveal that even in mixtures containing only 6.6 wt% of monomer, nano-sized LC domains can be formed by low-temperature polymerization of −20 °C that lead to the 'deformation-free' response. PChLC nanocomposites with reduced monomer concentrations exhibit improved tuning range of the refractive index and a short decay time of about 20 μs, making them more practical for real-life applications.
