Abstract

SiO2 cryogels (SCG) with a low thermal conductivity was used for transparent heat insulation coatings. SCG dispersion in organic solvent was prepared by sand milling, and the paint was composed of SCG dispersion as a functional filler and polyacylic resin as a binder. The paint was coated on PET film and then pasted on a glass substrate to form the filmed glass. The results showed that the particle sizes of SCG in the dispersion were almost below 100 nm, and the organic dispersion had a good stability. The coating with SCG dispersion exhibited a remarkable shielding effect in the near infrared waveband as well as a high transmittance above 80% in the visible light. The heat insulation temperature of SCG filmed glass was 4 °C compared with the blank glass. The transparent heat insulation coating with SCG will be developed for solar control and energy saving applications.
