1. Aerogel Finishing A Nanoporous Thermal Obstacle
Aerogel insulation coating is a breakthrough product born from the strange physics of aerogels– ultralight solids constructed from 90% air trapped in a nanoscale porous network. Think of “frozen smoke”: the tiny pores are so small (nanometers large) that they stop heat-carrying air particles from relocating easily, killing convection (heat transfer using air circulation) and leaving just very little transmission. This provides aerogel coverings a thermal conductivity of ~ 0.013 W/m · K, far less 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 finishings starts with a sol-gel process: mix silica or polymer nanoparticles right into a fluid to form a sticky colloidal suspension. Next, supercritical drying out gets rid of the fluid without falling down the vulnerable pore framework– this is key to preserving the “air-trapping” network. The resulting aerogel powder is mixed with binders (to stick to surfaces) and ingredients (for resilience), after that used like paint through splashing or cleaning. The final film is thin (typically
