Spectrophotometry and electrical conductivity studies of multiwall nanotubes dispersed in nematic liquid crystals

Spectrophotometry and electrical conductivity studies of multiwall nanotubes dispersed in nematic liquid crystals

Optical transmission and electric conductivity were measured as a function of temperature for thin layers of multiwall nanotubes (MWNTs) dispersed in a mixture of cyanobiphenyl nematic liquid crystals (LC) ZhK-1282. At MWNT concentrations of 0.01-0.15 wt. % , characteristic changes in transmission a...

Optical transmission and electric conductivity were measured as a function of temperature for thin layers of multiwall nanotubes (MWNTs) dispersed in a mixture of cyanobiphenyl nematic liquid crystals (LC) ZhK-1282. At MWNT concentrations of 0.01-0.15 wt. % , characteristic changes in transmission at the nematic-isotropic phase transition temperature evidence that MWNTs integrate into LC matrix in a manner similar to that of the conventional non-mesogenic dopants. The electrical conductivity shows a percolation-like behaviour at ultra-low MWNTs loading of LC matrix below concentration levels of ~0.01 wt. % , which reflects the high aspect ratio of the conductive filler and the existence of strong interactions between LC matrix and MWNTs.
