Aerogel, which is called "the black technology material that changes the world", has already shone in aerospace, building insulation, industrial insulation, military equipment and other fields. But you know what? There is more than one aerogel! Silicon dioxide, carbon, metal oxides, polymers... different types of aerogels have different properties and uses!
Today we will use a table to help you quickly understand the characteristics and applications of various aerogels!
Comparison of main types of aerogels
| Type | Main component | characteristic | application area |
| silica aerogels | SiO₂ | Ultra low density, super strong insulation, adjustable hydrophobicity | Building insulation, new energy insulation, industrial insulation |
| Carbon Aerogel | Graphene, carbon nanotubes | Conductive, ultra light, and super strong adsorption | Supercapacitors, battery electrodes, wastewater treatment |
| Metal oxide aerogel | Al₂O₃、TiO ₂, etc | Strong high-temperature stability and catalytic ability | Catalyst carrier, high-temperature insulation, filter material |
| Polymer aerogel | Polyimide, polyurethane, etc | Good flexibility and stretchability | Flexible insulation clothing, electronic device protection |
| composite aerogel | SiO ₂+carbon nanotubes, fibers, etc | Multi functional and enhanced mechanical performance | Bulletproof materials, high-temperature resistant composite materials |
