Abstract

Electrospray and electrospinning techniques have been successfully used to synthesize polyvinylalcohol/polyvinylpyrrolidone (PVA/PVP) nanoparticles and nanofiber composites. It is offers a simple method to make nanofibers using high voltage electric fields. Composites are made by dissolving PVA with concentrations of 5% w/w (nanoparticles) and 10% w/w (nanofibers), with PVP concentrating 5% in solvent aquades. The parameters of the electrospinning process are electrical voltage of 12kV, end of the needle to the collector as far as 20 cm, a flow rate of 0.20 mL/h, temperature, and humidity of the room (25±0.5°C, RH 45%) for 12 hours. The observed morphology results in the physical appearance of nanoparticles in the form of dots and nanofibers in the form of smooth and homogeneous surfaces. Nanoparticle forms are dot-like with an average diameter of 355 and 824 standard deviations of 120 nm and 173 nm. The homogeneity of nanoparticles and nanofibers has a price of 0.25 and 0.20.
