We present results of investigation of the phase state and the dynamic properties of the composite material, which consists of polymer polyethylene terephthalate (PET) porous films filled with a liquid crystal 4-n-pentyl-4'-cyanobiphenyl (5CB). In the experiments, methods of acoustic spectroscopy and dynamic correlation spectroscopy were used. New information about dynamic and viscoelastic properties...
Highly unusual thermochromic properties of large-scale shear-ordered photonic crystals are demonstrated. A simple theoretical model of the temperature dependence of this resonant Bragg scattering based structural colour is developed.
