Abstract :The aim of this study is to produce optically transparent nanofibers with adequate electrical conductivity for optoelectrical applications where transparency and conductivity are needed. Therefore, conducting polyacrylonitrile/silver nitrate (PAN/AgNO 3 ) nanofibers were produced by electrospinning with different deposition times ranging from 1 minute to 10 minutes. The effect deposition time on the sheet resistance and optical transparency of the nanofibers were investigated. The surface characteristics, electrical properties and transmittance values of the electrospun mats were evaluated. Nanofibers with diameters under 700 nm were obtained. With the increasing deposition time, the sheet resistance and transparency of the samples were decreased. In order to figure out the optimum deposition time, figure of merit of the samples were calculated. Figure of merit results showed that the sample deposited for three minutes had the best performance among the others. It was seen that the results were comparable with the literature and conducting PAN/AgNO 3 nanofibers are promising for future applications.
