Bu çalışmanın amacı grafit (GR) oranının grafit katkılı polivinilpirolidon (PVP) kompozit nanoliflerin morfolojisi ve ıslanabilirlik özellikleri üzerindeki etkisini araştırmaktır. Bu bağlamda, elektroeğirme yöntemi kullanılarak, PVP nanolif keçeler ile birlikte farklı oranlarda (%0,6, %1,2, %1,8, %2,4, %3, %3,6 ve %4,2 GR oranlarında (% PVP)) katkı içeren PVP/GR kompozit nanolif keçeleri üretilmiştir. Nanoliflerin morfolojileri ve çapları taramalı elektron mikroskobu (SEM) ile belirlenmiştir. Üretilen katkısız nanoliflerin ortalama çapı 218 nm olarak saptanmış iken, kompozit nanoliflerin çapları 170 nm ile 203 nm arasında değişmektedir. Keçelerin ıslanabilirliğini incelemek amacı ile temas açısı ölçümleri gerçekleştirimiştir. Beklentilerin aksine, grafit oranı arttıkça ıslanabilirliğin arttığı gözlemlenmiştir. Burada, grafitin son yıllarda keşfedilen hafif düzeyde hidrofilik özelliğinin etkili olduğu düşünülmektedir. Ayrıca, bu bulguların nanoliflerin elektriksel iletkenlikleri ile ilişkileri de incelenmiştir.

The aim of this study is to investigate the effect of graphite (GR) content on the morphology and wettability of polyvinylpyrrolidone (PVP) / GR composite nanofibers. For this purpose, PVP and PVP/GR composite nanofiber mats of various filler contents (0.6%, 1.2%, 1.8%, 2.4%, 3%, 3.6% and 4.2 % of GR (wt.% of PVP)) were fabricated by electrospinning. The morphology and diameters of the nanofibers were characterized by SEM. Average diameters of 218 nm for unfilled PVP nanofibers and between 170 nm and 203 nm for composite nanofibers were observed. The water wettability of the nanofiber mats was also characterized by contact angle measurements. Contrary to expectations, the results reveal an increase in the water wettability of composite PVP nanofiber mats with increasing graphite content. This evolution seems to be based on the mild hydrophilicity of graphite discovered in recent years. The relationship with nanofibers’ electrical conductivity was also examined.
