The late eighties, Larry Hrubesh led by researchers at Lawrence Livermore National Laboratory (LLNL) prepared the world's lightest silicon dioxide aerogels density is 0.003 g / cm 3, 3 times is just air. Soon after, Rick Pekala (LLNL) to prepare organic aerogels include resorcinol - formaldehyde aerogel, melamine - formaldehyde aerogel. Resorcinol - formaldehyde aerogel can be obtained pure pyrolytic carbon aerogel, which created a new field of study aerogels.

Into the nineties, for more in-depth research in the field of silicon dioxide aerogels. According to incomplete statistics, in recent years in various magazine articles about aerogels with over 3,000 articles. American Science magazine Popular Science as one of the top ten aerogel. 

Pohl Institute of Solid State Physics, Tongji University China in the early 1990s, the first in China to carry out research work aerogels, has accumulated a wealth of experience. In addition, the Institute of Physics and Chemistry, Tsinghua University, Shanxi Coal Chemistry, Nanjing University, China University of Science and Technology, National University of Defense Science and Technology, Beijing University of Chemical Technology, Wuhan University, Dalian University of Technology, also recently carried out research on aspects of aerogel . Overall, the aerogel expensive production cost, the material itself is difficult to overcome the low intensity, high brittleness and other shortcomings as a constraint to its wide application bottlenecks, and therefore become the key scientists from different countries to work together in future breakthroughs. Silicon dioxide aerogels is also worthy of study.
