Studies of Holographic Grating Formed in Polymer-Dispersed Liquid Crystal Films and Their Dynamical Behavior [PDF]

open access: yes, 2013
[[abstract]]We have developed an economic liquid crystal-polymer dispersion material that can be used for storing optical holographic images, The obtained results show that the written grating-holograms are permanent, but are electrically switchable ...

Porous Janus polymer single crystals via liquid-liquid phase separation at oil-water interface

open access: yesGiant
Coupling liquid–liquid phase separation (LLPS) with crystallization has emerged as an effective strategy for regulating polymer crystalline structures and elucidating crystallization mechanisms.

Self‐Cleaning Sensor Surfaces for Long‐Term Environmental Monitoring

open access: yesAdvanced Engineering Materials, EarlyView.
Long‐term use of unattended outdoor sensors without soiling or biofouling is achieved through generation of a micro‐ and nanorough cuvette surface by combing hydrophobic nanoparticles with fluorinated polymers, crosslinked and surface‐attached through CHic chemistry. The coating demonstrates self‐cleaning behavior and prolonged outdoor stability, which

Voltage induced spreading and liquid optical devices [PDF]

open access: yes, 2013
An experimental investigation has been carried out into Liquid dielectrophoresis (LDEP), in which dielectric forces are used to actuate bulk liquid spreading and to imprint a deformation pattern at a liquid air surface.

Discrepancies Between Micro Versus Macroscale Viscoelastic Properties in a Microplastic‐Tissue Composite Model

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.

Determination of χ from liquid-liquid phase data in ternary polymer systems (solvent/polymer/polymer) with hydrogen bonding

open access: yeseXPRESS Polymer Letters, 2008
Two different models accounting for the dependences of χ and g interaction parameters on both temperature and composition have been applied to different ternary polymer systems (TPS) solvent(1)/polymer(2)/polymer(3).

Polymer-dispersed liquid crystal elastomers

open access: yesNature Communications, 2016
Liquid crystal elastomers are promising for building actuators due to excellent thermomechanical response, but it is challenging to prepare them at macroscale with arbitrary shape.

Electro-Optical Properties of a Polymer Dispersed and Stabilized Cholesteric Liquid Crystals System Constructed by a Stepwise UV-Initiated Radical/Cationic Polymerization

open access: yesCrystals, 2019
Polymer-dispersed liquid crystal (PDLC) and polymer-stabilized liquid crystal (PSLC) are two typical liquid crystal (LC)/polymer composites. PDLCs are usually prepared by dispersing LC droplets in a polymer matrix, while PSLC is a system in which the ...

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

open access: yesAdvanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Modelling the transport of toluene liquid in protective polymer

open access: yes, 2015
The absence of adequate information about the phase change of liquid solvents within polymer-glove walls hinders the complete characterisation of the mass transfer of toluene liquid through the polymer membranes using the data obtained from ASTM F739 ...
