Material characterization demonstrates successful electrospinning of polyvinylpyrrolidone and Aloe vera dressings, indicating viable fabrication of plant-based wound care products.
The work aimed to develop a dressing for wound treatment using the polymer polyvinylpyrrolidone, ethanol, and crushed leaves of the medicinal plant Aloe vera, produced by the electrospinning method. Six samples were produced and observed by scanning electron microscopy (SEM), as well as by infrared spectroscopy (FTIR). The percentage distribution of fiber diameters was analyzed, and it was observed that increasing the mass of Aloe vera leaves in the solution tends to favor this distribution and increase the fiber diameter. The infrared spectra indicated the presence of the alcohol function, a six-atom ring of the vinyl group, and vinyl ethers. It was found that the addition of Aloe vera may lead to the exclusion of the alkene function in the samples. There was a similarity in the infrared line shapes for all the samples.
