Electrospinning method used to fabricate fibers both micrometers and nanometers scale. Nanofibers of Polyvinylpyrrolidone (PVP) have been developed using an electrospinning method. It is PVP acting as matrix and ethanol analyst as a solvent. We used the same concentrate of PVP I namely 10% (w/v) for three difference molecule-weight materials namely PVP 1.300.000 kg/mol (PVP-1), PVP 360.000 kg/mol (PVP-2) and PVP 40.000 kg/mol (PVP-3). The spinning process of the three molecule-weight PVP could be produced with various parameters, 0.3 flowrate, 10 kV voltage, and 12 cm needle length. Observation using a microscope shows the morphology of each solution (PVP-1), (PVP-2), (PVP-3) will generate large fibers, medium fiber, and nanofibers. The diameter of each fiber is 2620, 1760 and 1380. From the diameter analysis, we conclude that a smaller molecule-weight of PVP will obtain smaller fibers. The FTIR results give an overview of the interactions between PVP molecules that are shown against the PVP peaks. Nanofibers and nanoparticles can be applied in medicine, high-performance air filters, military and medical protective textiles, sensors, advanced composites, photo vault cells, and separation membranes. This study will show the difference form of PVP with the same concentrate for three difference molecule-weight.
