Epoxy polymer-based dielectric materials play a crucial role in advanced electronic devices and power equipment. However, high voltage-stress applications impose stringent requirements, such as strength, on epoxy polymers. Previously reported studies have shown promising material architectures the form of polymer–nanoparticle dielectrics, which can restrict movement high-energy electrons by interface charge traps associated with various interfacial regions. these inevitably traverse polymer...
Basin-type insulators are made by epoxy resin composite materials. Curing defects easily formed in basin-type insulators, and degrade their insulating performances. High curing exothermic rates of materials have deemed as the main cause formation. In this study, methyl tetrahydrophthalic anhydride (Me-THPA) was used to extend molecular chain liquid prepare with low rates. properties, weight distribution, stress, microstructures, surface flashover characteristics were investigated. The...
Layered ternary oxide LiNixMnyCo1–x–yO2 is a promising cathode candidate for high-energy lithium-ion batteries (LIBs). However, the capacity of LIBs significantly restricted by several factors, including repeated dissolution-regeneration interfacial film at high temperatures, dissolution transition metals, and increase impedance. Herein, new precycling strategy in suitable voltage scope room temperature proposed to construct uniform, thermally stable, insoluble cathode-electrolyte interface...
Surface electromyography (sEMG) plays a significant role in the everyday practice of clinic hand function rehabilitation. The materials and design current typical sEMG electrodes are rigid Ag/AgCl or flexible polyimide (PI) film, which cannot provide stable interface between skin for adequate long-term high-quality data. Thus, conformal, soft, breathable, wireless epidermal sensor systems have broad potential relevance to rehabilitation settings. Herein, we demonstrate stretchable array...
Producing high-purity hydrogen (H2) via highly efficient electrolytic water splitting remains a desired technique, which still holds considerable challenges. In this study, monodispersed IrCo hollow nanoparticles (HNPs) were prepared through one-pot process, affords excellent bifunctional electrocatalytic performance toward overall in an acidic medium. Alloying Ir with 3d transition metals (M) proved to be key component increasing oxygen evolution reaction (OER) activity by reducing the...
In order to study and analyze the aging mechanism of epoxy resin, characteristics resin were studied by molecular dynamics. Firstly, curing crosslinking bisphenol A with tetrahydrophthalic anhydride (THPA) good electrical properties was carried out. Then, process chain dynamics simulation, it verified infrared spectrum bond length distribution chains. The results show that chemical breaking occurs in small segments are produced, resulting decline mechanical resin. will produce H <sub...
Epoxy resin and acid anhydride curing system plays a significant role in the manufacture of electrical insulating materials due to its excellent dielectric property. However, theoretical strength epoxy is much greater than actual strength, one reasons for low residual stress cured resin. The thermal conductivity poor. After vacuum, heating, cooling series process process, different conditions rate will form temperature difference within With uneven volume shrinkage resin, be produce reduce...
Abstract Increases in rated voltage and power density of high gas insulated switchgears (GIS) impose stringent requirements on the diglycidyl ether bisphenol A (DGEBA)‐anhydride thermoset, which is widely used as insulation materials for GIS, higher mechanical heat‐resistant properties. In this paper, 3,4‐epoxycyclohexylmethyl 3,4‐epoxycyclohexanecarboxylate (AOO) was copolymerized with DGEBA ‐anhydride system to increase thermal properties thermosets. Based molecular dynamics simulation...

Silk fabric reinforced epoxy resin composites (SFRPs) were prepared using simple techniques of hand lay-up, hot-press and vacuum treatment, a series volume fractions silk reinforcements achieved. The impact properties dynamic mechanical SFRPs investigated pendulum testing method thermal analysis (DMTA). results suggest that reinforcement could greatly enhance the performances SFRPs. strength reached maximum 71 kJ/m2 for 60%-silk SFRP, which demonstrated potential defence impact- resistant materials.
