Abstract
The manufacture of nanofibers was carried out using the electrospinning method. This study used a chitosan solution with a concentration of 3% and a PVA solution with a concentration of 10%. Mixing the chitosan solution with the PVA solution used a volume: volume ratio of 1:4, 2:4 and 3:4. Furthermore, the electrospinning process was carried out with parameters including a voltage of 20 kV, a needle to the collector of 15 cm, and a flow rate of 5 ml/hour. The nanofibers produced from the electrospinning process were then characterized using Fourier Transform Infrared (FTIR) which serves to see the functional groups contained in the sample, Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX) which functions to see the morphology and constituent materials, and X-Ray Diffraction (XRD) serves to identify the crystalline phase in the material The spectrum of similarities between nanofiber chitosan/PVA with chitosan and PVA compounds proves that the produced nanofiber contains the chitosan and PVA group. Chitosan/PVA 1:4 nanofibers can be used as wound dressings because they form nanofibers better than others, where the resulting fibers are homogeneous with almost the same fiber size, namely 177.1 nm, tight, and smooth surface without any beads as evidenced by SEM characterization.
