Abstract The recent and fast‐growing trends related to the development of wearable technologies have raised need for efficient high‐performance energy storage devices having extra features such as flexibility lightweight. Polymer hydrogels, viscoelastic lightweight porous nanostructures with tunable surface structural properties, can play a crucial role in design these future devices. Herein, d...

A new liquid-crystal device for flexible display applications was developed using twofold polymerization process. The cell was fabricated from a homogeneous mixture of a liquid crystal and a polymerforming material. Caused by the spatially nonuniform rate of polymerization and wetting properties, largescale anisotropic phase separation of the liquid-crystal blend and the polymer precursor leads...

Core/shell (C/S)-structured upconversion nanophosphor (UCNP)-incorporated polymer waveguide-based flexible transparent displays are demonstrated. Bright green- and blue-emitting Li(Gd,Y)F4:Yb,Er and Li(Gd,Y)F4:Yb,Tm UCNPs are synthesized via solution chemical route. Their upconversion luminescence (UCL) intensities are enhanced by the formation of C/S structure with LiYF4 shell. The Li(Gd,Y)F4:...

Chemical vapor deposition (CVD) co-polymerization was used to fabricate polymer coatings, which comprise of reactive surface composition gradients. Two functionalized derivatives of [2.2]paracyclophane were fed into a two-source CVD system at a 180 ° angle, then copolymerized and deposited as a polymer gradient. Infrared and X-ray photoelectron spectroscopy (XPS) confirmed the compositional cha...
