▎ 摘 要
NOVELTY - Invention relates to nanotechnology and specifically to use of novel materials, such as polymer-graphene-gold and polymer-graphene-silver composites, obtained using chemical vapor deposition (CVD) method. Disclosed is a method of producing an optical filter based on graphene, which is a three-layer composite comprising a layer of polymer, a layer of monolayer graphene, synthesized by chemical vapor deposition (CVD) on a copper catalyst substrate and deposited on a transparent polymer surface, and a layer of metal nanoparticles. Layer of monolayer graphene is synthesized in a mixture of gases Ar/H2/CH4 at atmospheric pressure and transferred onto a polymer surface using a mechanical transfer method based on a thermo-pressing process to obtain a polymer-graphene composite. Layer of metal nanoparticles is sputtered onto the obtained polymer-graphene composite by laser ablation using laser pulses. Thickness of the coating of the polymer-graphene composite by metal nanoparticles is directly proportional to the number of laser pulses and is determined by the desired optical absorption coefficient in accordance with the relationship: K=0.0001776xx+0.4944, wherein K is absorption coefficient, and x is number of laser pulses. Polymer-graphene composite coating structure is configured by metal nanoparticles with provision of electromagnetic radiation absorption due to the plasmon resonance effect. USE - Nanotechnologies. ADVANTAGE - Obtaining an optical filter based on graphene, which enables to absorb up to 95% of electromagnetic radiation by using the plasmon resonance effect. 5 cl, 4 dwg
