Polymer-dispersed liquid crystals (PDLCs) exhibiting electro-optical (E-O) conversion capabilities facilitate modulation across the ultraviolet (UV) to infrared (IR) spectrum. In this study, a bilayer TiN-PVP/PDLC composite film device was prepared by utilizing commercially available polymers and nanoparticles enhance UV IR shielding efficacy. By optimizing ratio of polymer monomers within PDLC layer, superior E-O characteristics were achieved, which further augmented through incorporation...
Using the polymerization-induced phase separation (PIPS) method, bilayer polymer-dispersed liquid crystal (PDLC) films with a PDLC-PVA-PDLC structure were prepared in this work. It was found that all PDLC performance indexes affected by polymer mesh size after comparing microscopic morphology and electro-optical properties of samples different monomer ratios. Gd2O3 nanoparticles rhodamine B base fluorescent dyes introduced into optimized samples’ developed new functionalities. In addition,...
The commercial oxygen-free copper sheets were cold-rolled with reduction rates ranging from 20% to 87% rate and annealed at 400, 500 600 °C. microstructure texture evolution during cold-rolling annealing processes studied using optical microscopy (OM), the scanning electron (SEM) back-scattered diffraction (EBSD). results show that deformation textures of {123} (S) , {112} (Copper) {110} (Brass) continuously enhanced increase reduction. orientations along α-oriented fiber converged towards...
Cholesteric liquid crystals (CLCs) are widely used in the field of infrared (IR) modulation as a chiral photonic material with wavelength and polarisation selective reflection. However, there is ongoing interest discovering simpler method to harness crystal materials for IR shielding. In this study, CLC-based reflector was prepared. Broadband reflection CLC achieved by spin-coating layer PMMA-UV8080 generate vertical intensity gradient UV light. By optimising concentration absorber,...
Abstract AlGaN/GaN high electron mobility transistors (HEMTs) fabricated on a heterostructure grown by metalorganic chemical vapor deposition using an alternative method of carbon (C) doping the buffer are characterized. C-doping is achieved propane as precursor, compared to tuning growth process parameters control C-incorporation from gallium precursor. This approach allows for optimization GaN conditions without compromising material quality achieve semi-insulating properties. The HEMTs...
