Abstract
Bandages play a vital role in medical care by protecting wounds, promoting healing, and preventing infections. In recent years, their functionality has evolved significantly. Modern bandages are now engineered with advanced features such as antibacterial properties, breathability, moisture regulation, and even drug delivery capabilities. By incorporating innovative materials, like carbon-based nanofibers, these bandages offer additional advantages, including thermoregulation, rapid drying, and resistance to unpleasant odours—enhancing both effectiveness and patient comfort. Carbon-based bandages, in particular, show great promise due to these enhanced properties. This
research focuses on novel methods for the deposition of carbon materials onto textiles through electrospinning—an efficient technique that produces ultra-fine, nanoscale fibers from polymer solutions. By applying a high-voltage electric field, the solution is drawn into fibers that solidify and settle onto a collector surface. Electrospinning is widely used in fields like medical textiles, filtration, and sensing technologies, due to its ability to create lightweight, breathable, and highly functional materials with large surface areas.
In the present work, the application of nanowires on textile substrates was explored, optimizing deposition parameters to achieve a uniform coating on the textile substrate, with active nanofibers loaded with various C materials, for potential use in medical applications. Various carbon allotropes (diamond nanoparticles, carbon nanotubes-CNTs and graphene nanoplateles-GNPs) were integrated in different concentrations and combinations into polymeric matrices, and then electrospun into nanowires directly onto textile materials. This is a new approach for developing electrospinned active nanofibers and it was successful. The active nanofibers uniform coatings onto waved textiles
were achieved and characterised by XRD, SEM and Raman spectroscopy. The achieved materials will be tested for their antibacterial properties in the ongoing research.
