1. Aerogel Coating A Nanoporous Thermal Obstacle
Aerogel insulation finishing is a breakthrough product birthed from the strange physics of aerogels– ultralight solids constructed from 90% air entraped in a nanoscale permeable network. Envision “frozen smoke”: the tiny pores are so tiny (nanometers wide) that they quit heat-carrying air molecules from moving openly, killing convection (warmth transfer through air flow) and leaving only minimal transmission. This gives aerogel finishes a thermal conductivity of ~ 0.013 W/m · K, much less than still air (~ 0.026 W/m · K )and miles much better than conventional paint (~ 0.1– 0.5 W/m · K).
(Aerogel Coating)
Making aerogel coverings starts with a sol-gel process: mix silica or polymer nanoparticles into a fluid to create a sticky colloidal suspension. Next, supercritical drying out gets rid of the liquid without breaking down the breakable pore structure– this is essential to protecting the “air-trapping” network. The resulting aerogel powder is combined with binders (to stick to surface areas) and additives (for toughness), then used like paint via spraying or cleaning. The final film is slim (commonly
