Study Effect change amount addition of Sn2P2S6 nanoparticles on Thermal, Mechanical and Optical Properties of Polysiloxane Polymer

The paper included the influence of addition of Sn₂P₂S₆ nanoparticles on the Mechanical, Thermal, and Optical characteristics of liquid crystalline polymers with side chain. A constant Molecular weight was used (1.7 × 10⁶). The additive ratios were five different ratios of the added Sn₂P₂S₆ nanoparticles. It was noted that the voltage operation decreased with the increase of the ratio of the additive. The optical response (τ_on) was measured in opening case (when the electric field was applied) and closing time (τ_off) (when removing the electric field) by calculating the time interval between the primary and the new classification for liquid crystal polymer molecules caused by the electric field, Laser light while passing through the electrophoresis cell. The different addition ratio of Sn₂P₂S₆ particles, which had a fixed molecular weight from polymer, increased the density of the mesogenetic group associated with the polymer chain. This increased the effect of dipole torque in the C ≡ N group parallel to longitudinal axis of mesogenous unit, The dielectric anisotropy Δε has a lower optical response time (τ_on), (τ_off), thus improving the electro-optical properties of the system. The change in threshold voltage was measured at constant steps and under T_NI for a series of different additives' and found that the high additive additives had a small threshold voltage and this had to do with the polymer elasticity constant. Infrared spectrometer measurements were used to determine the coefficient of the directional arrangement of liquid crystals with a side chain. By determining the vibration of a specific package (C ≡ N) for absorption, it was found that the coefficient of the guideline is based on the temperature.
