Özet

In the last ten years, the market and studies related with nanofibers are considerably increasing in the areas such as filtration, energy harvesting, medical textile. Electrospinning is one of the most widely used techniques for nanofiber production. Mainly, two different types of electrodes in the electrospinning process are used: one is the conventional narrow nozzle and the other is the nozzle-less system. Conventional narrow nozzle is not preferred at industrial applications due to several problems such as low productivity, non-homogeneous coating and clogging. It is mostly preferred at laboratory applications, because of low price, wide production range and easy use. However, main disadvantages of nozzle-less system are high price (cost) and narrow production flexibility (range) compared to conventional narrow nozzle system. In this study, new novel nozzle prototype has been designed and studied to eliminate the disadvantages of conventional narrow nozzle system. From trials, it has been seen that production increased about 3 times compared to conventional narrow nozzle system, while homogenous coating could be obtained without clogging problem. It has also very low cost compared to nozzle-less system.
