Photorefractive properties in homogeneous and heterogeneous polymer / liquid crystal composites ∗
The photorefractivity of a photorefractive composite consisting of poly(N-vinylcarbazole) (PVK) doped with a non-room-temperature liquid crystal, 4-butyloxy4’-cyanobiphenyl (4OCB), and C60 was studied by means of measuring the two-beam coupling coefficients. The results show that the photorefractivity is enhanced by phase separation. PACS: 42.65; 61.30; 61.40 Interest in materials that exhibit ...
متن کاملPlasmonic Nanoparticles-Liquid Crystal Composites†
We report on the plasmonic properties of 6 nm gold nanoparticles that form highly stable solutions in the nematic liquid crystal 4-cyano-4-n-pentylbiphenyl (5CB). The nanoparticles were covalently functionalized with 4-sulfanylphenyl-4-[4-(octyloxy)phenyl]benzoate, which resembles the structure of the 5CB molecules. The solubility of these nanoparticles in 5CB was significantly higher than that...
متن کاملPolymer-dispersed liquid crystal elastomers
The need for mechanical manipulation during the curing of conventional liquid crystal elastomers diminishes their applicability in the field of shape-programmable soft materials and future applications in additive manufacturing. Here we report on polymer-dispersed liquid crystal elastomers, novel composite materials that eliminate this difficulty. Their thermal shape memory anisotropy is imprin...
متن کاملNanotube liquid crystal elastomers: photomechanical response and flexible energy conversion of layered polymer composites.
Elastomeric composites based on nanotube liquid crystals (LCs) that preserve the internal orientation of nanotubes could lead to anisotropic physical properties and flexible energy conversion. Using a simple vacuum filtration technique of fabricating nanotube LC films and utilizing a transfer process to poly (dimethyl) siloxane wherein the LC arrangement is preserved, here we demonstrate unique...
متن کاملPitch-Length Independent Threshold Voltage of Polymer/Cholesteric Liquid Crystal Nano-Composites
Polymer/cholesteric liquid crystal (ChLC) nano-composites consisting of mesogenic monomers and LCs have nano-sized LC domains dispersed in an anisotropic polymer matrix. They exhibit characteristics not observed in conventional ChLCs, such as sub-millisecond and “deformation-free” electro-optic tuning of the selective reflection band; however, their driving voltage is high compared to conventio...
