Magnetic properties of carbon nanotubes-natural rubber composites

Abstract

A natural rubber containing carbon nanotubes and carbonyl iron powder was prepared by a conventional technique using a two roll mill. The magnetic field version magnetization was conducted to study the magnetic characteristics of magnetorheological nanocomposites material (MNM) samples. This magnetic measurement is the induction method of scanning magnetic flux induced by the magnetic vibrating sample. The corresponding hysteresis graphs of MNE was plotted and the magnetization for was observed. The microstructure of the magnetic rubber was characterized by field emission scanning electron microscopy (FESEM). Results revealed that the Iron particles were relatively well dispersed in an NR matrix. It was found that the sample without CNT and iron powder dispersed magnetic rubber showed lower magnetization and retentively than the other.
