Poly(vinylidene fluoride)-based dielectric materials are prospective candidates for high power density electric storage applications because of their ferroelectric nature, breakdown strength and superior processability. However, obtaining a polar phase with relaxor-like behavior in poly(vinylidene fluoride), as required energy density, is major challenge. To date, this has been achieved using complex expensive synthesis copolymers terpolymers or via irradiation high-energy electron-beam...
Dielectric capacitors are very attractive for high power energy storage. However, the low density of these capacitors, which is mainly limited by dielectric materials, still bottleneck their applications. In this work, lead-free single-phase perovskite Srx(Bi1−xNa0.97−xLi0.03)0.5TiO3 (x = 0.30 and 0.38) bulk ceramics, prepared using solid-state reaction method, were carefully studied capacitor application. Polar nano regions (PNRs) created in material co-substitution at A-site to enable...
Seawater evaporation realized by solar-thermal conversion represents one of the most sustainable and effective strategies to obtain fresh water. Many approaches have been proposed achieve high efficiencies conversion, but their practical applications are limited low scalability. Herein, novel porphyrin/aniline-based conjugated microporous polymers (PACMPs) synthesized via a Buchwald-Hartwig coupling reaction, which then integrated with polyurethane sponges simple dip-coating technique. The...
Piezocatalysis, an evolving catalytic technology built on the piezoelectric properties of catalysts, breaks down barrier between mechanical energy and chemical energy. The potential difference that arises from deformation a material is commonly termed 'piezopotential'. Piezopotential has been demonstrated to facilitate manipulation band structure and/or charge carrier separation. Despite significant efforts design materials understand mechanism piezoelectrically enhanced chemistry through...
