Polivinil alkol (Pva) nanoliflerin üretiminde yenilikçi bir yaklasim: Santrifüjlü Lif üretimi

One of the emerging technologies for the nanofiber production is "centrifugal spinning". It is a compatible technique for industrial applications due to higher production rates compared to electrospinning, which is the most widely used method. In this study, poly(vinyl alcohol) nanofibers which are used in high value added products such as biomedical applications and lithium ion battery electrodes were produced via centrifugal spinning. Effect of production parameters (solution concentration, needle diameter, rotor speed and needle-collector distance) on fiber morphology was investigated with SEM images. Optimum conditions were determined as 10-15 wt% solution concentration, 6000-9000 rpm speed, 0.5 mm needle diameter and around 150 mm needle-collector distance. Also, nanofibers with diameters below 200 nm were produced at industrial rates.
