ANALISIS SIFAT LISTRIK NANOKOMPOSIT Fe0,5-C0,5 [Analysis Of Electrical Properties Of Fe0.5-C0.5 Nanocomposite]

Abstract

Analysis of electrical properties of Fe0.5-C0.5 nanocomposite has been carried out. This study was conducted to obtain carbon-based composite material that has higher electrical properties in the framework of its application in electronics field. Fe0.5-C0.5 nanocomposite was prepared from a mixture of Fe powder and graphite powder with weight ratio of 1: 1. Then it milled for 50 hours. Identification of X-ray diffraction (XRD) pattern showed that during such 50- hours milling process, the intensity of the diffraction peaks was dominated by phase C (002) and Fe (101). The results of XRD data analysis showed the grain size of powder of about 25 nm and 36 nm for C and Fe, respectively. Surface morphology measured by SEM showed that the size of the Fe-C powder before milling process >10 µm, and after milled for 50 hours showed a size of about 50 nm.The analysis results of particle size and surface area of Fe0.5-C0.5 nanocomposite obtained, i.e. 50 nm and 705m2/g, respectively.Thus, the process of milling for 50 hours against a mixture of Fe0.5-C0.5 composite can produce Fe0.5-C0.5 nanocomposite. Electrical properties of nanocomposite Fe0.5-C0.5 measured by a LCR (Inductance : L, Capacitance : C, and Resistance : R) meter showed the value of conductivity of 2.56 S / cm and capacitance of 0.15 μF at frequency of 100 kHz. Fe0.5- C0.5 nanocomposite shows the higher the electric properties when compared with the Fe-C micro-sized composite.
