Abstract

Metode electrospinning merupakan salah satu metode pembuatan nanofibers yang banyak digunakan oleh para peneliti karena kualitas nanofibers yang dihasilkan cukup menjanjikan dengan biaya pembuatan yang cukup murah. Penelitian ini dilakukan untuk mengetahui morfologi, dimensi dan struktur carbon-nanofibers PVA yang difabrikasi dengan teknik electrospinning. Juga untuk mengetahui pengaruh suhu karbonisasi terhadap morfologi carbon-nanofibers yang dihasilkan. Digunakan variasi suhu karbonisasi sebesar 200oC dan 250oC untuk mengkarbonisasi nanofibers berbahan PVA Teknis dan PVA Pro-Analis. Dengan melakukan uji XRD dan SEM untuk mengetahui struktur dan morfologi carbon-nanofibers yang dihasilkan, maka didapatkan struktur amorf pada nanofibers yang dihasilkan dengan bentuk serat acak pada carbon-nanofibers PVA baik Teknis maupun Pro-Analis. Akan tetapi keduanya memiliki bentuk yang cukup berbeda, dimana carbon-nanofibers PVA Pro-Analis cenderung lurus tanpa beads sedangkan PVA teknis lebih bergelombang. Diameter untuk PVA Pro-analis cenderung menyusut, yaitu 46 nm pada suhu 200oC dan 41 nm pada suhu 250oC. Sedangkan pada PVA Teknis nilai diameternya cukup besar pada suhu 250oC yaitu sekitar 103 nm dibandingkan pada suhu 200oC sebesar 57 nm. Hal ini terjadi karena pada suhu 250oC nanofibers meleleh sehingga menyatu satu sama lain dan yang teramati adalah bagian yang meleleh sehingga tampak lebih besar. Carbon-nanofibers berhasil terbentuk dengan sempurna oleh nanofibers PVA Teknis yang dikarbonisasi dengan suhu 250oC yang ditunjukkan oleh hasil uji XRD yang membentuk pola seperti pola carbon amorf.

The electrospinning method is one of the nanofibers manufacturing methods that is widely used by researchers because the quality of the nanofiber produced is quite promising and the manufacturing cost is quite cheap. This research was conducted to determine the morphology, dimensions and structure of PVA carbon-nanofibers fabricated by electrospinning technique. Also to determine the effect of carbonization temperature on the morphology of the carbon-nanofibers produced. Carbonization temperature variations of 200oC and 250oC were used to carbonize nanofibers made from Technical PVA and Pro-Analyst PVA. By conducting XRD and SEM tests to determine the structure and morphology of the resulting carbon-nanofibers, the amorphous structure of the nanofibers produced in the form of random fibers on the PVA carbon-nanofibers, both technical and pro-analytical, was obtained. However, both have quite different shapes, where the carbon-nanofibers PVA Pro-Analyst tends to be straight without beads while the technical PVA is slightly wavy. The diameter for Pro-analyst PVA tends to shrink, namely 46 nm at 200oC and 41 nm at 250oC. Meanwhile, in technical PVA, the diameter value is quite large at a temperature of 250oC, which is around 103 nm compared to a temperature of 200oC at 57 nm. This happens because at a temperature of 250oC the nanofibers melt so that they merge with each other and what is observed is the melted part so that it looks bigger. The carbon nanofibers were successfully formed perfectly by the Technical PVA nanofibers which were carbonized at a temperature of 250oC which was shown by the XRD test results which formed a pattern like the pattern of amorphous carbon.
