Dispersions of carbon nanotubes and organomodified clay platelets in cholesteric liquid crystals

Dispersions of carbon nanotubes and organomodified clay platelets in cholesteric liquid crystals

Comparative studies were carried out of cholesteric liquid crystal dispersions of anisotropic nanoparticles of different types, namely, essentially rod-like carbon nanotubes (CNT) and plate-like exfoliated particles of organo-modified Laponite and montmorillonite clays. The characteristic properties...
