Trace addition of a hydrophilically tuned nonionic amphiphilic polymer additive enables hydrophobic confinement aqueous electrolyte that considerably prolongs the cycle life Zn-ion devices and widens temperature operation.
Abstract Aqueous zinc‐metal batteries are prospective energy storge devices due to their intrinsically high safety and cost effectiveness. Yet, uneven deposition of zinc ions in electrochemical reduction side reactions at the anode interface significantly hinder development application. Here, we propose a solvation‐interface attenuation strategy enabled by frustrated tertiary amine amphiphilic dipolymer electrolyte additive. The configuration superhydrophilic segments with covalently bonded...
Abstract As a potential candidate for next‐generation energy storage systems, Li–O 2 batteries (LOBs) with their attractive theoretical density have triggered great interest. However, tough issues of sluggish oxygen reduction reaction/oxygen evolution reaction (ORR/OER) kinetics, poor rechargeability, superoxide‐derived side reactions, and Li‐metal corrosion in LOBs limit practical applications. Herein, poly(2,2,2‐trifluoroethyl methacrylate) (PTFEMA) additive is introduced into the typical...
Abstract Achieving stable zinc‐metal anodes is pivotal to realizing high‐performance aqueous batteries (AZMBs). The construction of a functional polymer interface layer on the anode surface confirmed as an effective strategy for mitigating dendrite growth and side reactions, thereby significantly enhancing stability anode. However, polymers capable withstanding electrolyte environments over long term typically suffer from elevated interfacial impedance, which hinders Zn 2+ transport. Here,...
ABSTRACT In order to obtain nitrile‐butadiene rubber (NBR) with both high strength and toughness, composites a double network were prepared by introducing poly (acrylonitrile‐ co ‐butyl acrylate) elastomer. The P(AN‐ ‐BA) elastomer was randomly copolymerized acrylonitrile (AN) butyl acrylate (BA). second formed the crystal crosslinking of tensile toughness 460% 305% NBR, respectively. curves differential scanning calorimetry (DSC) exhibited peaks representing melting in heating ‐BA)/NBR...
ABSTRACT Graphene oxide (GO) and silicon dioxide (SiO 2 ) nanoparticles have been hybridized for improving the mechanical dynamic properties of nitrile rubber (NBR). SiO were homogeneously dispersed on surface between layers GO, new hybrid formed (GO/SiO 2) had better thermal stability than GO. To evaluate properties, GO/SiO /NBR nanocomposites prepared by solution blending methods. It was observed that tensile strength increased in a larger grade GO/NBR nanocomposites, while elongation at...
ABSTRACT Hydrogels are a promising candidate for applications in biomedicine and bioengineering, but their mechanical properties often restrict applications. To improve the performance of poly(vinyl alcohol) (PVA) hydrogels, we introduced sodium carboxymethylcellulose (CMC), graphene oxide (GO) into them. We prepared series composite hydrogels composed PVA, CMC, GO with epichlorohydrin as chemical crosslinker. used Fourier transform infrared spectroscopy X‐ray diffraction to characterize...
Graphene oxide (GO), modified with anti-aging agent p-phenylenediamine (PPD), was added into nitrile rubber (NBR) in order to improve the thermo-oxidative stability of NBR. The modification GO and transformation functional groups were characterized by Fourier transform infrared spectroscopy (FTIR), Raman, X-ray diffraction (XRD). Mechanical performances NBR composites before after aging recorded. results dynamic mechanical analysis (DMA) show an increased storage modulus (G’) a decreased...
Maleic anhydride (MAH) was grafted onto low-density polyethylene (LDPE) by a solution approach with dicumyl peroxide (DCP) as initiator and xylene solvent. The effects of various experimental conditions on the grafting degree (GD, wt%), such DCP concentration (A), MAH (B), reaction time (C), temperature (D) for addition (E), were investigated an orthogonal experiment. results demonstrated that had greatest influence GD, while minimal GD. A copolymer high GD (up to 4%) obtained under optimum...
Hydrogels are promising materials, but because of their weak mechanical performance, further applications limited. To enhance the strength hydrogels, physical cross-linking was introduced by use hydrophobic unit diacetone acrylamide (DAAM) to form points. The homopolymer DAAM exhibited a high glass transition temperature above 80 °C, which confirmed DSC. existence glassy and phases in hydrogel XRD test results. properties were satisfactory, with maximum tensile 1.96 MPa, rapid recovery...

Rheological properties of hydrolyzed polyacrylamide (HPAM) solutions were measured in oscillatory and flow shear. In shear the storage loss moduli increased as concentrations increased, but they decreased salinity increased. The relaxation spectra plotted using Kontogiorgos method. As shown spectra, number density segmental units at first then peaks shifted split into several concentration With increasing, motion increase became broader. tests, curves viscosity versus rate fitted by a power...
