FIELD: physics. ^ SUBSTANCE: nanocomposite antireflection coating in form of a thick film contains a polymethyl methacrylate polymer matrix filled with 1-10 nm silver nanoparticles with mass concentration 30.5% and modified viscous polymethyl methacrylate in volume ratio 10:1, respectively. The method of making a nanocomposite coating in form of a thick film involves dissolving a polymethyl methacrylate-based composition containing 1-10 nm silver nanoparticles with mass concentration 30.5% until formation of a starting liquid composition with kinematic viscosity from 26.1 0.7 to 804 cS and polymer concentration of 0.15-0.31 pts.wt, stabilising the obtained starting composition by adding, while stirring, a modifying additive in form of polymethyl methacrylate with kinematic viscosity 84.20.5 cS in volume ratio10:1, respectively, which ensures formation of an adsorption-solvate layer on the surface of particles of the starting composition, followed by depositing the obtained process nanocomposite onto a solid underlying surface and drying. ^ EFFECT: obtaining an antireflection coating of high quality and high efficiency. ^ 4 cl, 5 dwg, 5 tbl |
