Synthesis of Organic Aerogels and Factors Affecting on their Structure

Organic polymer aerogels have received much attention due to the recent development in industrial application of aerogels. A lot of researches have been done about the synthesis of various organic polymer aerogels and carbon aerogels. This paper presents a brief review of the literature on synthesis methods of resorcinol-formaldehyde, polyurethane, cellulose and carbon aerogels. Since structure and properties of organic aerogels are influenced by synthetic conditions, the effect of temperature, PH of solutions, catalysts and monomer concentrations are discussed.
