Özet
Gelişen teknoloji ve giyilebilir elektronikler gibi enerjiye bağımlı cihazlarla birlikte enerji talebi her geçen gün artmaktadır. Nanojeneratörler son 20 yıldır araştırmacılar tarafından yoğun bir şekilde çalışılmaktadır. Nanolif ve polimer bazlı cihazlar bunlar arasında en popüler olanlardır. Bu çalışmada çekirdek-kabuk nanofiber yapısı önerilmiş ve çekirdeğin kabuk yapısına oranı üretilmiştir. Nanoliflerin çapı ve piezoelektrik performansları karakterize edildi ve birbirleriyle karşılaştırıldı. Sonuç olarak maksimum 3:1 oranından maksimum 2,1 V voltaj, maksimum voltaj 28,28 µA, maksimum 31,31 µW güç ve maksimum 184,17 µW/g.cm-2 güç yoğunluğu elde edildi (PVDF: TPU).
Energy demand is increasing daily by the improving technology and energy dependent devices such as wearable electronics. Nanogenerators have been studied by the researchers for the last 20 years intensively. Nanofiber and polymer based devices are the most popular ones among the others. A core-shell nanofiber structure was proposed in this study and the ratio of the core to the shell structure was produced. Diameter of the nanofibers and piezoelectric performances were characterized and compared with each other. As result, a maximum voltage of 2.1 V, maximum voltage of 28.28 µA, a maximum power of 31.31 µW, and a maximum power density of 184.17 µW/g.cm-2 were obtained from the maximum ratio of 3:1 (PVDF:TPU).
