About Aerogel. Aerogels have been in existence for more than 80 years. Invented in 1931 by Dr. Samuel Kistler at the College of the Pacific in California, silica aerogel is a lightweight solid derived from gel in which the liquid component of the gel has been replaced with gas.

Figure 6: SEM images of cellulose aerogel monoliths (a) 4 % wt., (b) 5 % wt. and (c) 6 % wt. cellulose concentrations. The mechanical behavior of cellulose aerogel is determined by compression deformation test. Both Young’s modulus and the 0.2 % offset compressive yield strength are given in Figure 7.

Welcome to Aerogel.org. Aerogel is a synthetic porous ultralight material derived from a gel, in which the liquid component for the gel has been replaced with a gas without significant collapse of the gel structure. Aspen Aerogels designs, develops & manufactures aerogel insulation.

The reinforced aerogel showed slightly tighter structure and very good water stability and mechanical strength. FTIR disclosed the chemical bonds formed between chitosan and cellulose. Aerogel blankets are composites of silica aerogel particles dispersed in a reinforcing fiber matrix that turns the brittle aerogel into durable and flexible insulating materials. In this study, silica aerogel was loaded on glass wool with different concentrations (0–18.6%) and morphological and thermal characteristics of the aerogel blankets were studied.

hybrid aerogels were made using 3-aminopropyltriethoxysilane (APTES) endcapped polyamic acids and tetramethoxysilane (TMOS) as precursors. Polyimide crosslinked aerogels were characterized by TGA, SEM, FT -IR, BET, solid state NMR and gas pycnometry. These hybrid aerogels exhibit high thermal stability and have potential

The MX/rGO aerogel not only combines the rGO’s large specific surface area and the MXene’s (Ti3C2Tx) high conductivity but also exhibits rich porous structure, which leads to Investigadores de Coimbra desenvolvem aerogel sem pós e partículas O projeto permitiu a evolução do aerogel possibilitando benefícios para o espaço, a aeronáutica e até mesmo para a Encontre Aerogel no MercadoLivre.com.br!
