Aerogel Coatings vs Paint: Thermal Insulation Redefined silica aerogel paint

1. Aerogel Coating A Nanoporous Thermal Obstacle

Aerogel insulation covering is a development product born from the strange physics of aerogels– ultralight solids made of 90% air trapped in a nanoscale permeable network. Visualize “icy smoke”: the little pores are so tiny (nanometers broad) that they quit heat-carrying air molecules from moving freely, killing convection (heat transfer using air circulation) and leaving only very little transmission. This provides aerogel layers a thermal conductivity of ~ 0.013 W/m · K, far lower than still air (~ 0.026 W/m · K )and miles better than traditional paint (~ 0.1– 0.5 W/m · K).


(Aerogel Coating)

Making aerogel coatings starts with a sol-gel procedure: mix silica or polymer nanoparticles into a fluid to develop a sticky colloidal suspension. Next, supercritical drying out gets rid of the fluid without breaking down the vulnerable pore structure– this is vital to preserving the “air-trapping” network. The resulting aerogel powder is mixed with binders (to stay with surface areas) and additives (for sturdiness), after that used like paint by means of splashing or brushing. The last film is slim (typically
