Electrical and Optical Studies of Hydrogen Bonded Ferroelectric Liquid Crystals Dispersed with MWCNT.

Two hydrogen bonded ferroelectric liquid crystals (HBFLC) are dispersed with multi-walled carbon nanotubes (MWCNT) for achieving better thermal and electrical performance. Interesting feature of the present communication is the enhancement in the enthalpy value pertaining to isotropic-nematic transition in MWCNT doped liquid crystals compare to its pure counter parts. Dielectric relaxations studies are carried out in the pure and the MWCNT doped systems. It is observed that doping of MWCNT elevated the activation energies considerably. Optical shuttering action in one of the complex dispersed with MWCNT are discussed. [ABSTRACT FROM PUBLISHER]
