Electrospinning of Poly(ethylene-co-vinyl alcohol)‎ Nanofibres Encapsulated with Ag Nanoparticles for Skin Wound Healing

الملخص EN

Skin wound healing is an urgent problem in clinics and military activities.

Although significant advances have been made in its treatment, there are several challenges associated with traditional methods, for example, limited donor skin tissue for transplantation and inflammation during long-term healing time.

To address these challenges, in this study we present a method to fabricate Poly(ethylene-co-vinyl alcohol) (EVOH) nanofibres encapsulated with Ag nanoparticle using electrospinning technique.

The fibres were fabricated with controlled diameters (59 nm–3 μm) by regulating three main parameters, that is, EVOH solution concentration, the electric voltage, and the distance between the injection needle tip (high-voltage point) and the fibre collector.

Ag was added to the nanofibres to offer long-term anti-inflammation effect by slow release of Ag nanoparticles through gradual degradation of EVOH nanofibre.

The method developed here could lead to new dressing materials for treatment of skin wounds.
