Glycerol /Phthalic Anhydride Novel Nano Composite for Microwave Absorbing Applications

Abstract

High-efficiency radar wave absorbing material was prepared utilizing nanoparticles poly (glycerol /phthalic anhydride), and the effect of using these nanocomposites with thermal paint on the properties of electromagnetic absorbing was analyzed and investigated. Results show that when the percentage of nano polymers is increased from 1% to 3%, with the presence of 2.5% of iron oxide, the reflectivity loss value rises dramatically. For the reflectivity up to 27.2dB at a frequency of 8.3 GH and a bandwidth of (8.1-8.2GH), there is a clear attenuation of the radar waves, which is confined within a bandwidth of GH (9-9.3GH). This material can be utilized as a high- efficiency radar wave absorbing applications.

Nano Revolution: “Tiny tech, big impact: How nanotechnology is driving SDGs progress"

“…Nanocoating materials can effectively absorb or scatter radar waves [ 48 , 187 , 188 ], making items undetectable by radar and, thus, improving stealth capabilities (such as Ghost ships, and ghost airplanes).…”

Phthalic anhydride (PA): a valuable substrate in organic transformations

“…77 In 2022, glycerol/PA novel nanocomposite was introduced for microwave absorbing applications. 78 Velayutham and coworkers in 2009 demonstrated the synthesis and characterization of polyurethane (PUR) coatings derived from polyols synthesized with glycerol, PA, and oleic acid. The utilized polyols were designated as Alk28, Alk40, and Alk65, in which 28%, 40%, and 65% of oleic acid was present, respectively.…”
