Popis:	Silicon dioxide sol with oligoethers can be used to obtain antireflecting coatings on silicate glass at various baking temperatures of the coating: 400, 300, and 200°C. At an optimal concentration of 4.0 mass % of oligoether based on PPG-725 in a sol, the maximum light transmission of 99.7%, and the refractive index of the nanoporous coating of 1.23 do not depend on the baking temperature in the range from 200 to 400°C. Silicon dioxide sol with a 4.0 mass % of ALM-10 give a maximum light transmission of 99.7% and a refractive index of the nanoporous coating of 1.23 at a baking temperature of 300–400°C. A maximum light transmission of the glass with a coating of 98.7% and the refractive index of 1.27 at an optimal concentration of 8.0 mass % of oligoether based on PEG-200 were obtained at baking temperatures of 300–400°C.
