Advancements in Research and Applications of PP-Based Materials Utilizing Melt-Blown Nonwoven Technology

Polymers, Journal Year: 2025, Volume and Issue: 17(8), P. 1013 - 1013

Published: April 9, 2025

Melt-blown nonwoven materials have demonstrated significant advancements in a multitude of industrial sectors, mainly due to their high production efficiency, extensive specific surface area, and narrow aperture. The demand for melt-blown has increased further recent time, particularly the wake novel coronavirus (COVID-19) pandemic. Polypropylene (PP) is extensively used research its low cost, weight, easy processing, made from it share similar characteristics. We systematically summarize technology applications PP-based over last few years. First, principles processes that govern micro/nano fibers are described. Then raw process reviewed. After these, we highlight use key fields, including media filtration, oil–water separation, heavy metal ions removal, organic pollutants removal battery separator. Finally, summary suggest some potential future directions materials.

Highly Permeable and Liquid-Repellent Textiles with Micro-Nano-Networks for Medical and Health Protection

Nano-Micro Letters, Journal Year: 2025, Volume and Issue: 17(1)

Published: April 9, 2025

Abstract Current protective clothing often lacks sufficient comfort to ensure efficient performance of healthcare workers. Developing textiles with high air and moisture permeability is a potential effective solution discomfort medical clothing. However, realizing the facile production textile that combines safety remains challenge. Herein, we report fabrication highly permeable (HPPT) micro/nano-networks, using non-solvent induced phase separation synergistically driven by CaCl 2 fluorinated polyurethane, combined spraying technique. The HPPT demonstrates excellent liquid repellency comfort, ensuring dry microenvironment for wearer. exhibits not only hydrostatic pressure (12.86 kPa) due its tailored small mean pore size (1.03 μm) chemical composition, but also (14.24 mm s −1 ) (7.92 kg m −2 d owing rational combination porosity (69%). offers superior compared commercially available materials. Additionally, elucidated molding mechanism inducted diffusion–dissolution-phase separation. This research provides an innovative perspective on enhancing theoretical support regulating structure during separations.

ACS Applied Nano Materials, Journal Year: 2023, Volume and Issue: 6(24), P. 23496 - 23505

Published: Dec. 12, 2023

The demand for personal protective equipment increased exponentially during the COVID-19 epidemic, and shortage of medical clothing has prompted consideration recycling clothing. However, it is still challenging to maintain an excellent barrier property functionality material after cyclic sterilization. Herein, autoclavable nanofibrous laminated composite fabrics with waterproof breathability were fabricated by electrospinning lamination technology. TPU/PEI membranes hydrophobically treated then two construct sandwich structure fabrics. showed robust hydrostatic pressure 38 kPa, high antisynthetic blood penetration level 4, filtration efficiency 99.7%, outstanding water vapor transmission rate 5.2 kg m–2 d–1. Furthermore, benefiting from high-temperature resistance, dimensional stability, tensile strength membranes, as-prepared could be autoclaved 10 times without great degradation liquid properties. successful preparations shed light on reusable design provide useful guidance solve critical issue materials shortage.
