Multi-walled carbon nanotubes-ferroelectric liquid crystal nanocomposites: effect of cell thickness and dopant concentration on electro-optic and dielectric behaviour

Popis výsledku v původním jazyce

Several advanced nanocomposites of FLC material doped by the functionalised MWCNTs have been designed in order to establish the effect of the cell thickness and dopant concentration on behaviour of advanced self-assembling materials. The results were obtained for 0.00wt%, 0.05wt% and 0.07wt% concentrations of the dopant for 5μm and 12μm thick cells. Fastening of switching time and increase in permittivity of non-doped FLC and nanocomposites as a function of increased cell thickness can be attributed to the change in the anchoring energy and DC conductivity of the non-doped and doped systems. An increase of the spontaneous polarization with concentration of MWCNTs doping can be explained on the basis of π-π stacking between MWCNTs and FLC layers. The increase of the response time with doping concentration may correspond to a strong anchoring energy. Using the MWCNTs as a dopant can be a tool to tune electro-optic of FLC materials to make them usable for photonics.
