Transparent ATO/epoxy nanocomposite coating with excellent thermal insulation property

Transparent antimony-doped tin oxide (ATO)/epoxy nanocomposites, as glass thermal insulation coating, were prepared by incorporating ATO nanoparticles into a transparent epoxy matrix. The effect of ATO content on the optical and thermal insulation property of ATO/epoxy coating was studied. The results show that the ATO/epoxy coating with 1 wt ATO has excellent optical properties, that is, visible light transmittance above 50 and shading coefficient of 0.54 are simultaneously achieved. In addition, the large temperature difference between the chambers coated respectively with the ATO/epoxy glass sheet and the common glass sheet indicates that the prepared ATO/epoxy nanocomposite coating has excellent thermal insulation property.
