Synthesis of Chiral Hybrid Nickel Based Nanocomposites Based on Graphene Oxide, Single-Wall Carbon Nanotube, and Polyaniline: Characterization, Analyzing Nanocomposite Structure, and Investigating Radar Absorption Properties

In this research, chiral nickel nanocomposite was synthesized, which has the property of stealth by the ability to absorb microwave waves. In the synthesis of this nanocomposite, the first, graphene oxide synthesized with the method of Homer with paraphenylenediamine was reacted and then using carbon dioxide salts, a carbon-carbon bond between modified graphene oxide and a single-walled carbon nanotube was established. Then, in the presence of this hybrid, aniline polymerization was carried out in acidic medium using ammonium peroxy sulfate as a primer, which resulted in the production of graphene oxide, a single-wall carbon nanotube, and polyaniline. The doping of this nanocomposite in ammonia solution, then washing and drying the doping of the nanocomposite with chiral tartaric acid, created the chiral nanocomposite. Afterward, nickel ions were loaded with hydrazine as a reducing agent on a chiral nanocomposite. All of the synthesized materials were identified by the infrared spectrum and the results indicated that the synthesis of chiral nickel nanocomposites was successful. Structural and morphological analysis of synthetic compounds were used for Scanning Electron Microscopy (SEM). The crystalline properties of synthetic compounds were also investigated by X-ray Diffraction (XRD). Ultimately, the microwave absorption spectra of the composite were investigated.
