Abstract With the increasing development of intelligent robots and wearable electronics, demand for high-performance flexible energy storage devices is drastically increasing. In this study, symmetric microsupercapacitors (MSCs) that could operate in a wide working voltage window were developed by combining laser-direct-writing graphene (LG) electrodes with phosphoric acid-nonionic surfactant liquid crystal (PA-NI LC) gel electrolyte. To increase flexibility enhance conformal ability MSC to...
Abstract Polyurethane films based on renewable sources were prepared as an alternative to petroleum‐based polyurethane. The effects of the structure and ratio diisocyanate components polymer properties investigated. Hexamethylene (HMDI) diphenylmethylene (MDI) chosen in synthesis. Membranes by casting‐evaporation technique characterized for their gas permeability, film mechanical properties. oil‐based membranes found be suitable wound dressing applications.
In this work, to construct a sunlight-powered energy storage system, single wall carbon nanotubes (SWCNTs)-based symmetric micro-supercapacitors (MSCs) were fabricated by one-step, facile spraying method. The electrodes exhibited satisfactory conductivity with sheet resistance of 275 Ω/sq. Moreover, potassium hydroxide-poly(vinyl alcohol) (KOH-PVA) and phosphoric acid-nonionic surfactant liquid crystal (PA-NI LC) gel electrolytes prepared applied design all-solid-state MSC devices. Compared...
Proton-conducting gel electrolytes offer significant advantages for supercapacitors. Among various acids, phosphoric acid (H3PO4·H2O, PA) has the highest proton conductivity use as a supercapacitor electrolyte. Compared with commonly used acidic and basic (H2SO4 KOH), high specific capacitance of approximately 620 F g−1 was attained PA under 0.1 A test conditions in combination reduced graphene oxide (rGO) symmetric electrode. Moreover, electrolyte further improved by confining it to liquid...
