In this paper, the optical properties of randomly mixed consisting of poly(methyl methacrylate) and Chromium chloride have been investigated. The samples of composites have been prepared by adding Chromium chloride to poly(methyl methacrylate) with different weight percentages from Chromium chloride with polymer and different thickness. Results showed that the absorbance increases with the increase of the concentration of CrCl 2 . The absorption coefficient, extinction coefficient, refractive index and real and imaginary parts of dielectric constants are increasing with the increase of the CrCl 2 concentration. The energy band gap is decreased with the increase of the CrCl 2 concentration.

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, ( S ¯ ) for liquid crystals with a side series. The orientational order parameters ( S ¯ ) rely on temperature with various molecular weights and the threshold voltage.
