In the field of wound treatment, chronic wounds pose a significant burden on medical system, affecting millions patients annually. Current treatment methods often fall short in promoting effective healing, highlighting need for innovative approaches. Electrospinning, technique that has garnered increasing attention recent years, shows promise care due to its unique characteristics and advantages. Recent studies have explored use electrospun nanofibers demonstrating their efficacy cell growth tissue regeneration. Researchers investigated various materials electrospinning, including polymers, ceramics, carbon nanotubes (CNTs), metals. Hydrogel, as biomaterial been widely studied matrix. When combined with it can be used develop dressings multiple functions. This article is review application electrospinning technology treatment. It introduces current research status areas pathophysiology, preparation technology, dressing development, hoping provide references directions future research.

Electrospun polytetrafluoroethylene (PTFE) fibers in membrane distillation applications

AIMS Materials Science, Journal Year: 2024, Volume and Issue: 11(6), P. 1179 - 1198

<p>Polytetrafluoroethylene (PTFE) is a fully fluorinated linear polymer with (CF₂-CF₂)_n backbone. High molecular weight PTFEs are chemically inert while possessing excellent hydrophobic surface properties attributed to their low energy. These characteristics make PTFE an candidate for membrane distillation application among all other polymers. In this review, the electrospinning processes of fibers discussed in detail focus on various effects resulting fiber morphologies and structures. Due high chemical resistance solvent solubility, typically electrospin carrier, such as polyvinyl alcohol (PVA) and/or polyethylene oxide (PEO), using emulsion followed by sintering process. The amount emulsion, types carriers, parameters, conditions have interconnected morphological structures PFTE (e.g., beading or continuous fibers). addition, electrospun further functionalized methods co-electrospinning polymers well incorporations metallic (ZnO) inorganic particles (POSS) improve performance distillation. Water contact angles, permeation fluxes, salt rejection rates, hours operations reported fibrous membranes demonstrate feasibility applications. general, article provides scientific understanding engineering distillation.</p>
