Effect of Molecular Weight on Electro – Optic Switching Times of Liquid Crystal Polymer Doped with Ceo2 Nanoparticles

Nonlinearity liquid crystal cell which doped with Ferroelectric nanoparticles characters studied in this paper according to their eclectic absorption. Polysiloxin series with side chain liquid polymers used with side chain polymers and molecular weight ran This study consternate on polymers electro. optic characteristic with various molecular weights by using the mesogenic units and a stable polysiloxane. Suspension sensitivity or Electro-visual response to the mark of the used electric field, a real character to electric liquid crystals. The addition of CeO2, nanoparticles to polymer rise dielectric anisotropy and minimize response times. It observed that the voltages raised with molecular weight rising, and when intensity value rise, we gain voltage operating. Spectrometer used infrared measurements to locate the orientational order parameters, $\left(\overline{S}\right)$ for liquid crystals with a side series. The orientational order parameters $\left(\overline{S}\right)$ rely on temperature with various molecular weights and the threshold voltage. (paper)
