Abstract

Kapasitor berbasis nanofiber telah berhasil dibuat dengan menggunakan poli(akrilonitril) dan grafit. Metode penelitian yang digunakan adalah penelitian murni. Material yang digunakan adalah poli(akrilonitril), grafena dari grafit dan DMF. Poli(akrilonitril) dengan konsentrasi 10% (b/b), DMF dengan konsentrasi 90% (b/b) dan grafena dari grafit dengan konsentrasi 0,05 gr (FPG1), 0, 15 gr (FPG2) dan 0,25 gr (FPG3). Metode produksi serat menggunakan electrospinning (NLI Instrument HVPS). Hasil morfologi yang ditunjukkan oleh SEM berbentuk seperti untaian pita secara kontinu, panjang dan tanpa manik-manik (bead). Diameter serat berukuran 220 nm – 538 nm yaitu 220 nm (FPG1), 348 nm (FPG2) dan 538 nm (FPG3). Hasil XRD menujukkan struktur kristal PAN/grafena berupa semikristal. Hasil CV menujukkan nilai kapasitansi 8,34 F/g (FPG1), 11,66 F/g (FPG2) dan 13,83 F/g (FPG3). Hasil EIS menunjukkan nilai Rs sebesar 0,7 Ω (FPG1), 0,32 Ω (FPG2) dan 0,3 Ω (FPG3) dan Nilai Rp sebesar 27,32 Ω (FPG1), 15,55 Ω (FPG2) dan 13,15 Ω (FPG3).
