Ultra-light porous solids with exceptional thermal insulation for apparel and technical textiles
- Technology Readiness Level: 6/9
- Impact: 5/5
- Investment: 4/5
Aerogels are porous solids in which the liquid component has been replaced by gas, yielding extremely low density and thermal conductivity. Silica aerogels are the most common; carbon, polymer, and other variants exist. Applications include thermal insulation for pipelines, aerospace, and buildings; transparent insulative "glass"; and lightweight structural materials. Early uses and diffusion; commercialization is advancing. Challenges include cost, fragility, and moisture sensitivity. Research continues into flexible aerogels, transparent variants, and scalable production.
