Light-Powered Liquid Crystal Polymer Network Actuator Using TiO Nanoparticles as an Inorganic Ultraviolet-Light Absorber.

Recently, the design and fabrication of light-powered actuators have attracted immense attention because of the manufacturing of intelligent soft robots and innovative self-regulating devices. Accordingly, a liquid crystal polymer network (LCN) provides a promising platform due to its reversible and multistimulus-responsive shape-changing behaviors. In particular, doping nanoparticles with exclusive properties into the LCN can produce interesting results.

Temperature-dependent optical properties of some mixtures nematic liquid crystal.

The presence of optical anisotropy in liquid crystals (LCs) has caused these materials to have dual refractive indices: ordinary (n) and extra-ordinary (n). Many fundamental information about LCs can be found by looking at these refractive indices. In this work, the refractive indices of four mixtures nematic liquid crystal (NLC) have been studied as a function of temperature, and the relevant functions were then calculated.
