| Abstract: | Production of magnetite (nano-Fe3O4)-coated carbon fibers (MCCFs) composites using the electrophoretic deposition (EPD) technique has been investigated in the present research. Fe3O4 nano-powder was synthesized by the reduction of Fe (III)-tri-ethanolamine (TEA) in an aqueous alkaline solution. By the deposition of nano-Fe3O4 particles distributed stably in a suspension on the surface, a uniform and compact Fe3O4 thin-film was fabricated on nitric acid-treated carbon fiber. According to the results, the strongest reflection loss (RL) of MCCFs was recognized to be ?11 dB at 10.37 and 11.4 GHz for a layer of 1.7 mm in thickness. EPD was introduced as a suitable method for the production of MCCFs due to its low cost, easy productivity and time efficiency as well as the high absorption properties of the resulting MCCFs compared with the previous reported works. |
