Dielectric Studies of Carbon Nanotube Doped Ferroelectric Liquid Crystal Films

Abstract

A small amount (0.05% & 0.1% wt. /wt.) of multiwall carbon nanotube doped ferroelectric liquid crystal sample cell were prepared and studied. The dielectric measurements have been investigated as a function of temperature and frequency in the frequency range of 50Hz to 1MHz. A decrease in dielectric permittivity (~40%) in 0.1% CNT doped FLC sample was found over 0.05% doped sample. The relaxation frequency of goldstone mode was found ~ 119-161Hz and 116-182Hz respectively for 0.1% and 0.05% CNT doped cells.
