Separator is an essential component of lithium-ion batteries (LIBs), playing a pivotal role in battery safety and electrochemical performance. However, conventional polyolefin separators suffer from poor thermal stability nonuniform pore structures, hindering their effectiveness preventing shrinkage inhibiting lithium (Li) dendrites. Herein, we present robust, high-temperature-resistant polyimide (PI) separator with vertically aligned uniform nanochannels, fabricated via ion track-etching technology. The resultant PI track-etched membranes (PITEMs) effectively homogenize Li-ion distribution, demonstrating enhanced ionic conductivity (0.57 mS cm

Superspreading-Based Fabrication of Poly(methyl methacrylate) Films with High Toughness for Ultra-Wideband Flexible Transparent Antenna

Materials, Год журнала: 2025, Номер 18(10), С. 2183 - 2183

Опубликована: Май 9, 2025

With the rapid advancement of Internet Things (IoT) technology, ultra-wideband flexible transparent antennas have garnered substantial attention for their potential applications in wireless communication devices. Poly(methyl methacrylate) (PMMA), renowned its exceptional optical properties and favorable processing characteristics, has been extensively utilized as a substrate material antennas. However, intrinsic brittleness PMMA substrates poses significant limitation such In this study, we introduce superspreading strategy to address complex trade-off among transparency, toughness, dielectric electronics through molecular disorder engineering. The films fabricated via exhibit visible transmittance 85–95% at 400 nm, toughness 9 × 10⁵ J/m3 (representing an enhancement 150–225% compared conventional methods), frequency-stable permittivity (εr = 3.6 ± 0.05) within 9–12 GHz range. These also feature precisely tunable thickness range 5.5–60 μm. PMMA-based antenna demonstrates gain 2–4 dBi relative bandwidth 40%, thereby confirming suitability applications. Collectively, research presents promising candidate development

Hydratable Janus Membranes with Robust Antiwetting Pores for Stable Membrane Distillation of Saline Oily Wastewater

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Май 16, 2025

Janus membranes, composed of a hydrophilic surface layer and hydrophobic substrate, are potential candidates for membrane distillation (MD) to prevent organic substance induced wetting in saline oily wastewater treatments. However, owing insufficient hydrophobicity pore surfaces, traditional substrates suffer from limited MD performance stability when water penetrates through the layer. Herein, we present polyvinylidene fluoride (PVDF) nanocomposite with robust antiwettability stable desalination wastewater. Hydrophobic silica (SiO2) nanoparticles used build nanostructures on surfaces significantly enhance their preventing wetting. The superhydrophilic tannic acid/Fe (TA/Fe) provides hydratable promote molecule absorption, facilitate evaporation rate, effectively impede oil/surfactant/gypsum contaminants. As result, TA/Fe-PVDF/SiO2 shows (32 h) high flux 25.2 kg m-2 h-1 salt rejection (>99.9%) solution. This work promising approach develop high-performance membranes antiwetting ability treatment.
