Development of Liquid Crystalline Hydrogel Soft-Actuator Working under Body Temperature Range

Communications: Short-range dynamics of a nematic liquid-crystalline phase.

Using x-ray photon correlation spectroscopy, we studied the dynamics in the nematic phase of a nanorod suspension. The collective diffusion coefficient in the plane perpendicular to the director varies sharply with the wave vector. Combining the structure factor and the diffusion coefficient, we find that the hydrodynamic function of the phase decreases by more than a factor of 10 when going fr...

Time dependence of colour-temperature characteristics of liquid-crystalline thermoindicators

2014 The temperature and time dependencies of the wavelength of selective light scattering of cholesteric liquid crystals dispersed in various polymers are studied. The stability of liquid crystals is found to be determined by the gas permeability of polymers. The injection of the antioxidants into the polymer increases essentially the lifetime of the capsulated liquid crystals. REVUE DE PHYSIQ...

Force and stroke of a hydrogel actuator

Hydrogels that undergo a volume phase transition in response to an external stimulus are of great interest because of their possible use as actuator materials. The performance of an actuator material is normally characterized by its force–stroke curve, but little is known about the force–stroke behavior of hydrogels. We use the theory of the ideal elastomeric gel to predict the force–stroke cur...
