Electrospinning Equipment: Piezoelectric properties in electrospun polyimide nanofibers for Harsh Environments 2025-03-06

High-temperature-resistant piezoelectric fluorinated polyimide (FPI) nanofibers were fabricated via electrospinning. Traditional piezoelectric materials exhibit insufficient thermal stability for extreme environments, prompting the incorporation of 6FDA into polyimide (PI) to enhance piezoelectricity and thermal resistance. The resulting FPI nanofibers demonstrated a decomposition temperature exceeding 550°C, a glass transition temperature (Tg) of ~260°C, and stable piezoelectric outputs up to 10V under mechanical excitation (sensitivity: 478.72 mV/N; response/recovery time: 15 ms). Additionally, they exhibited superhydrophobic properties (water contact angle = 139.6°), ensuring operational stability in harsh conditions. These findings establish FPI nanofibers as promising candidates for flexible sensors, wearable electronics, and energy harvesters in extreme environments.

Electrospinning Equipment: Electrospun Carbohydrate Polymer Nanofibers for Advanced Wound Dressings 2025-03-06

This review explores electrospun carbohydrate polymer nanofibers as advanced wound dressings. Conventional dressings struggle with infection control, moisture retention, and tissue regeneration. Electrospinning produces high-surface-area nanofibers with porosity and tailored mechanical properties, offering superior wound management. Natural polymers like alginate, cellulose derivatives, chitosan, starch, hyaluronic acid, and dextran are highlighted for their biocompatibility, cell-supporting capabilities, and renewable sources. Current innovations include blend/coaxial/triaxial electrospinning techniques to enhance functionalization. Challenges remain in polymer stability, mechanical performance, and scalable production. Future directions focus on optimizing biodegradation rates, reducing cytotoxicity, and developing smart systems for real-time wound monitoring and drug delivery. Systematic research is critical to advancing these materials toward clinical implementation.

Electrospinning Equipment:Fabrication of Multilayer Bioabsorbable Composite Vascular Stent 2025-03-05

This study develops a hybrid composite vascular stent integrating oxidized starch (OS)-Fe₃O₄ nanoparticles and polycaprolactone (PCL) nanofibers. OS is oxidized with FeCl₃/FeCl₂/H₂O₂ to enhance hydrophilicity, while PCL nanofibers are produced via electrospinning to ensure uniform diameter (1.2–1.5 μm), improving mechanical strength. Thermoplastic starch (TP) plasticized with sesame oil/citric acid/glycerol forms self-adhesive layers, enabling multilayer bonding. CO₂ laser cutting shapes the stent into an origami-inspired tube (600–650 μm strut width, 1.9–2 mm diameter). The composite exhibits enhanced tensile strength (25–30 kPa), stable compressive properties (~25 kPa after 12 weeks), and controlled degradation (mass loss over 20 weeks). Biocompatibility tests confirm hemolysis <0.5%, endothelial cell attachment (>70% viability), and normal clotting parameters. This design balances mechanical robustness, biodegradability, and endothelialization potential, addressing PCL’s limitations

Electrospinning Equipment: ZnO-MnO₂ Co-Modified Porous Carbon Nanofiber Electrodes for Supercapacitors 2025-03-05

This study develops ZnO and MnO₂ co-modified hierarchical porous carbon nanofiber (ZnMnO-HPC) electrodes for high-energy-density supercapacitors. Using an electrospinning machine, a hierarchical porous structure was introduced, enhancing energy density through the synergistic effects of ZnO and MnO₂. The ZnMnO-HPC electrode exhibited excellent electrochemical performance, achieving a high specific capacity of 401.77 C/g at 0.5 A/g and maintaining 201.29 C/g at 5 A/g. When assembled into an asymmetric capacitor with an activated carbon electrode, it delivered an energy density of 38.37 Wh/kg at 407 W/kg and 19.5 Wh/kg at 12,800 W/kg. Additionally, it demonstrated remarkable cycle stability, retaining 92.61% of its capacity after 10,000 cycles. These results highlight the potential of ZnMnO-HPC as a promising electrode material for next-generation high-energy-density supercapacitors.

Superior-Strong Carbon Nanofibers via Electrospinning Machine and PAN Jetting 2025-03-04

This study introduces a method to produce superior-strong carbon nanofibers via additive nanostructuring and carbonization of polyacrylonitrile (PAN) jetting. The research focuses on manipulating PAN fiber microstructures at the nanoscale and converting them into continuous carbon nanofibers with enhanced mechanical properties. By analyzing electrostatic jetting processes and shear stress distribution, the study achieves a core-shell structure in PAN fibers with zigzag and helical conformations. These fibers are deposited on various substrates and carbonized to create continuous nanofibers with diameters around 20 nm and tensile strengths up to 212 GPa. The method not only maximizes nanoscale effects but also introduces multifunctionality, such as superhydrophilicity and piezoelectric properties, offering new opportunities for advanced energy storage and high-performance materials.

High-Strength TiO₂/TPU Fibers via Electrospinning Machine 2025-03-04

Industrial dye wastewater, especially containing triphenylmethane dyes like rhodamine B (RhB), is a severe water pollution issue. Photocatalysis is a promising treatment method, but nanostructured photocatalysts face problems in liquid - phase systems. This study aimed to solve these problems by preparing TiO 2/TPU composite fibers. The research prepared highly durable TiO 2/TPU composite fibers with high TiO 2 content (>30 wt.%) via wet spinning using 1D electrospun TiO 2 nanofibers (TNFs). The composite fibers showed enhanced mechanical properties compared to pure TPU fibers due to the fiber reinforcement principle. Among them, the 1 - 2 TNF/TPU composite fibers exhibited remarkable photocatalytic performance, achieving a 99.47% removal rate of RhB in 270 minutes. The unique structure of the composite fibers, including the orientation of 1D TNFs, strong interface between TNF and TPU matrices, and hollow and porous structures, contributed to high strength and photocatalytic activity.

Electrospinning Equipment:MgO/MgCO₃/PCL Fibers Enhance Nerve Regeneration via Wnt Pathway 2025-03-03

This study develops a multi-gradient electrospun MgO/MgCO₃/PCL nanofiber scaffold, fabricated using an electrospinning machine, to achieve controlled Mg²⁺ release for peripheral nerve regeneration. Structural characterization confirmed the scaffold’s tunable degradation properties, while in vitro studies demonstrated that Mg²⁺ enhanced Schwann cell proliferation, migration, and repair phenotype transition. Transcriptome sequencing and western blot analysis identified the Wnt5a/β-Catenin pathway as a key regulatory mechanism. In vivo experiments using a 10 mm sciatic nerve defect model in rats showed that the 10% MgO/MgCO₃/PCL scaffold significantly improved axonal regeneration, remyelination, and functional recovery, outperforming higher Mg concentrations. This study provides a novel biomaterial strategy for long-term nerve repair, bridging electrospun fiber engineering and molecular mechanisms, and establishing a foundation for the clinical translation of magnesium-based scaffolds.

Electrospinning Equipment: Smart Iontophoretic Microneedle Patch for Long-Lasting Local Analgesia 2025-03-03

Acute pain from medical procedures such as venipuncture and minor surgeries poses challenges for effective pain management. Traditional lidocaine (LIDO) injections and topical creams are limited by needle phobia and poor skin permeability. This study introduces an iontophoresis-driven fiber-based microneedle patch (IFMP) that integrates dissolving microneedles with iontophoresis (ITP) for controlled, long-lasting, and non-invasive lidocaine delivery. The IFMP system, fabricated using a micro-molding technique with a cotton fiber canvas, enables precise drug release through smartphone-controlled electrical modulation. Experimental evaluations confirmed the IFMP’s strong mechanical properties, effective skin penetration, and biocompatibility. In vivo studies demonstrated rapid onset and prolonged analgesia, surpassing conventional lidocaine creams and microneedle systems. The integration of ITP significantly enhances transdermal drug permeation, allowing for on-demand pain relief. Addit
