1. Aerogel Coating A Nanoporous Thermal Obstacle
Aerogel insulation finishing is a breakthrough product born from the unusual physics of aerogels– ultralight solids made of 90% air trapped in a nanoscale porous network. Imagine “icy smoke”: the small pores are so small (nanometers vast) that they stop heat-carrying air molecules from moving freely, eliminating convection (warmth transfer using air circulation) and leaving only minimal transmission. This gives aerogel coatings a thermal conductivity of ~ 0.013 W/m ยท K, far lower than still air (~ 0.026 W/m ยท K )and miles much better than standard paint (~ 0.1– 0.5 W/m ยท K).
(Aerogel Coating)
Making aerogel finishes starts with a sol-gel process: mix silica or polymer nanoparticles into a fluid to form a sticky colloidal suspension. Next, supercritical drying out eliminates the liquid without breaking down the delicate pore structure– this is key to maintaining the “air-trapping” network. The resulting aerogel powder is blended with binders (to stay with surfaces) and ingredients (for toughness), after that applied like paint via spraying or brushing. The final movie is thin (typically
