When nanofibers and nanoparticles combined at the nanoscale, they create new features in the material and therefore new areas of use. In this study, dense medium plasma technique is used for nanoparticles synthesis which is novel, cost-efficient, and fast technology when is compared with other common nanoparticles synthesis techniques. It allows initiation and sustainment of discharges in a co-existing liquid/vapor medium at atmospheric pressure and offers a significantly higher efficiency for the processing of liquid-phase materials in comparison to other existing plasma technologies. Carbon-based nanoparticles are synthesized from an arc sustained in benzene (purity, 99.5%) between iron electrodes by the lab-made-dense medium plasma system. Processing parameters are summarized as volume of benzene;30 ml, distance between plasma electrodes: 0.5 cm, discharge time: 10 second. Then, separated carbon nanoparticles are integrated with the polyvinylpyrrolidone (PVP) nanofibers produced by the electrospinning method. Nanocomposite fiber processing parameters are optimized (polymer concentration, 7.8-8.0 %w/v; ratio of polymer solution /nanoparticle; distance of electrode, 10-25 cm; processing time 5-30 min) and than they are characterized by contact angle measurements, scanning electron microscopy and transmission electron microscopy. At the same time, electrical conductivity of nanocomposite mats are also tested for foreseeing usage in biomedical application. Results showed that diameter of carbon nanoparticles are 46±8nm. New material, carbon nanoparticle containing PVP nanofiber mats are presented in transmission electron microscopy. It is a super hydrophilic mat material (static contact angle is lower than 10 °). According to the optimization of processing parameters, the diameter of nanocomposite fibers are able to reach 150 ±75nm. Electrochemical impedance spectroscopy is used to determine the nanofiber mat resistance. After accurate calibration and fitting of the impedance spectra to the equivalent circuit, nanocomposite mat resistance is found to be dramatically higher than that for the bare PVP nanofiber mat resistance. According to these results, a potential biomedical application of new material is discussed. In this study, carbon nanoparticles containing PVP nanofibers have been fabricated via electrospinning technique for the first time and a new class of mat membranes based on dense medium plasma based nanocomposites have been prepared and evaluated for medical devices. .It has a great potential to use as biocompatible, light, insulator new material.
