Sintesis dan Karakterisasi Sifat Magnetik dan Listrik Komposit Film Berbasis Fe-Filled Multiwalled Nanotube Carbon

Abstract

Research and development have synthesis and characterization of magnetic and electrical properties of composite films based on Fe-Filled Multiwalled Carbon Nanotubes (MWNT) with the Simple Mixing method. In this study used MWNT and Fe-MWNT from the last research. MWNT mixed with PVA and PVA mixed with Fe-MWNT, and then do evaporation process where composite is allowed to stand for 2 days at the temperature room until finally forming a thin film. Analysis of X-Ray Diffractometer shows that the addition of MWNT and Fe-MWNT will enhance the conductivity from the number of broad grain size. Morphological structure of PVA/MWNT and PVA/Fe-MWNT also obvious by using Scanning Electron Microscopy. LCR analysis showed that PVA/MWNT are insulators and PVA/Fe-MWNT are conductors. As for the magnetic properties of PVA/MWNT is diamagnetic and PVA/Fe-MWNT is paramagnetic test results with Vibrating Sample Magnetometer.
