The sample with 15 wt.% loading of cobalt ferrite (CoFe2O4) increases the electrical permittivity as a result of Maxwell-Wagner effect and induces ferrimagnetic properties in PP composites. By increasing the CoFe2O4 loading to 55 wt.%, the magnetization and relative permittivity were substantially raised. Interestingly, this high loading which was comparable to the percolation threshold, did not affect the coercivity. Both low and high CoFe2O4 loadings have insignificant effects on magnetic permeability spectra. The results suggest that the melt mixing is a facile route to incorporate high loading of magnetic powder into plastics, leading to composites of enhanced electromagnetic properties. 2019-10-14T14:01:08Z 2019-10-14T14:01:08Z 2019-10 Article International Journal of Nanoelectronics and Materials, vol.12(4), 2019, pages 459-466 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/62438 en Universiti Malaysia Perlis (UniMAP) |
