1. Aerogel Finish A Nanoporous Thermal Barrier
Aerogel insulation coating is a breakthrough product birthed from the strange physics of aerogels– ultralight solids made of 90% air entraped in a nanoscale permeable network. Think of “frozen smoke”: the tiny pores are so small (nanometers vast) that they stop heat-carrying air particles from relocating easily, killing convection (heat transfer through air flow) and leaving only minimal transmission. This gives aerogel finishings a thermal conductivity of ~ 0.013 W/m ยท K, much less than still air (~ 0.026 W/m ยท K )and miles much better than traditional paint (~ 0.1– 0.5 W/m ยท K).
(Aerogel Coating)
Making aerogel finishes begins with a sol-gel process: mix silica or polymer nanoparticles right into a liquid to create a sticky colloidal suspension. Next, supercritical drying removes the liquid without breaking down the vulnerable pore framework– this is vital to preserving the “air-trapping” network. The resulting aerogel powder is blended with binders (to stick to surface areas) and ingredients (for sturdiness), after that applied like paint via spraying or cleaning.
