Modification in dielectric properties of SWCNT doped ferroelectric liquid crystals

Temperature-dependent electro-optical and elastic properties of carbon nanotube doped polar smectogen octylcyanobiphenyl

“…Up to date, the most of the studies on LC-CNT mixtures have been devoted to nematogen LCs, especially pentylcyanobiphenyl, 5CB [21][22][23][24][25][26], 4-ethoxybenzylidene-4′-n-butylaniline, EBBA [16,[27][28][29], 4-butoxybenzylidene-4′-n-butylaniline BBBA [3], E7, commercial eutectic mixture of alkyl and alkyloxycyanobiphenyls and triphenyls [30][31][32][33][34][35][36]. Additionally, there exist some reports on ferroelectric LC (FLC)-CNT mixtures [37][38][39][40]. The studies based on smectogen LCs, exhibiting partial positional order in addition to long-range orientational order, have rarely been reported.…”

Electro-optical properties of nanodispersions based on ferroelectric thiobenzoates

“…On the other hand, Gupta and co-workers show that SWCNT/ FLC system possess high conductivity. [12] They point out that at higher voltage SWCNTs produce a vast amount of electrons which increase the conductivity of the doped FLC system resulting in the decrease in value of the dielectric permittivity. We suggest that interaction between carbon nanotubes and FLC molecules is supporting the dipole moment of the system increase and hence increases polarization.…”

Carbon Nanotubes in Liquid Crystals: Fundamental Properties and Applications

“…Effect of SWCNTs on dielectric and electro-optical properties of doped FLCs has been studied [213][214][215]. A noticeable changes in relaxation behavior as well as increase of spontaneous polarization and relative permittivity with slight slower response has been observed for the doped system [214].…”
