Abstract
Methods of forming hybrid aerogels are described. The methods include forming a hybrid aerogel from a metal oxide precursor and a branched telechelic copolymer, e.g., co-hydrolyzing and co-condensing the metal oxide precursor and the branched telechelic copolymer. Aerogels and aerogel articles, including hydrophobic aerogels and hydrophobic aerogel articles are also described.
