Abstract
Microwave absorbing materials plays a crucial role in reducing pollution created due to the electromagnetic radiation and several defence applications. This paper reports about the microwave absorption property of combined form of Carbon Nano fibres (CNF) and Ferric Oxide Nano powder (Fe2O3). Ferric Oxide Nano powder is deposited on the fibres of CNF using hydrothermal autoclave method. The samples of CNF- Ferric Oxide Nano powder with different weight percentages is fabricated and the microstructure and microwave absorbing properties are studied. By varying the amount of CNF and Ferric Oxide Nano powder the microwave absorbing and electromagnetic properties are modulated. For investigating the synergistic effects between CNF and ferric powders, different mass ratios of CNF to ferric oxide Nano powder have been synthesized and helped in enhancement of the effect between the magnetic loss and dielectric loss to achieve high microwave absorption. These results might be inspiration for the future to create microwave absorbing materials which are light weight.
