Honey-based PET or PET/chitosan fibrous wound dressings: effect of honey on electrospinning process.
In this study, fibrous mats were fabricated via electrospinning from solutions of polyethylene terephthalate (PET), PET/chitosan, and PET/honey at different concentrations. The effect of honey and chitosan on electrospinning process was investigated and compared. Fibers containing chitosan had a beaded or ribbon-like/branched morphology, but this morphology improved in the presence of honey. The diameter of electrospun fibers decreased with an increased ratio of honey in PET solution. In addition, fiber deposition area in the collector increased by increasing the honey content. PET/chitosan and PET/honey fibrous mats reached an equilibrium water content in 15 min and their water uptake capacities, which are important for exudating wounds, were found in the range of 280-430% on dry basis. Cytotoxicity evaluation demonstrated that fibers exhibited no cytotoxic activity. This study discloses that PET fibrous mats especially electrospun in the presence of honey could be proposed as potential wound dressing materials owing to their improved processing abilities besides their suitable structural properties.
