Fabrication and characterization of fe3o4 tio2 hybrid particle dispersed flexible rubber composite for emi shielding

Abstract

The current work aims to fabricate a flexible elastomeric newlinemicrowave shielding composite material with excellent mechanical and newlinethermal properties using Fe3O4 and titania hybrid nanoparticles. The primary newlineobjective of this research was to develop a flexible natural rubber composite newlinewith a high strength and thermal stability and a higher wave attenuation newlinecoefficient against microwave frequencies between 8 and 20 GHz. The coprecipitation newlinemethod was used to prepare the Fe3O4 nanoparticles, and the newlineparticle size was confirmed using a transmission electron microscope. newlineSimilarly, X-ray diffraction analysis was used to confirm the phase structure newlineof prepared Fe3O4. newlineThe results indicated that the formed Fe3O4 crystal structure was newlinesimple cubic and exhibited a highly crystalline pattern. Similarly, Fe3O4- newlineTitania hybrids were prepared via low energy ball milling and the newlinehybridization effect confirmed via transmission electron spectroscopy. newlineAccording to the results, the hybridization process was carried out effectively newlineover time. Following that, the Fe3O4-Titania hybrids were surface-treated with newline3-Aminopropyltriethoxysilane via a wet solution method to prevent newlineagglomeration. Two-roll milling with recommended process parameters was newlineused to create the natural rubber flexible composite. newlineThe mechanical, wear, and thermal properties of the material were newlineimproved as a result of the improved tensile strength, modulus, wear newlineresistance, and mass decomposition. The composite with the highest tensile newlinestrength of 60 MPa contains 1.0 vol. % Fe3O4-TiO2 particles. Similarly, the newlinewear results indicate that the COF and Sp. wear rate are the lowest newline
