A Review of Aerogels and Their Application as a Multi-functional Building Material ZHUGE Yan1, a 1Faculty of Engineering and Surveying, University of Southern Queensland, Queensland, Australia aZhuge@usq.edu.au Keywords: aerogels, construction materials, nano materials, solid mechanics.
Aerogels have been in existence for many years; however, the engineering applications of aerogels have been limited due to their poor mechanical behaviour.
Silica aerogels are attractive materials with low-density and high porosity assemblies of silica nanoparticles and possess desirable physical properties, such as lowest thermal conductivity among all solid materials (less than 20mWm-1K-1) and high acoustic impedance [4, 5].
However, the engineering applications of aerogels have been limited due to their poor mechanical behaviour (fragility).
As a new type of cellular solids, although discovered many years ago, the engineering applications of aerogels have been limited due to their fragility and hydrophilicity [7].
