A hyperbranched organic aerogel, and methods for making and using the same, are disclosed. The aerogel can include a core/flexible spoke type structure. The aerogel can include flexible spokes that can include 3 to 8 flexible hydrocarbon-containing materials bonded to a core material. The core and flexible hydrocarbon-containing spacer material can include 1 to 3 A-X functional groups, where A is silicon (Si), phosphorous (P), or sulfur (S), and X is oxygen (O) or nitrogen (N). L'invention concerne un aérogel organique hyper-ramifié, et des procédés de fabrication et d'utilisation de celui-ci. L'aérogel peut comprendre une structure de type noyau/rayons souples. L'aérogel peut comprendre des rayons souples qui peuvent comprendre de 3 à 8 matériaux souples contenant des hydrocarbures liés à un matériau de noyau. Le noyau et le matériau d'espacement souple contenant des hydrocarbures peuvent comprendre de 1 à 3 groupes fonctionnels A-X, A étant du silicium (Si), du phosphore (P), ou du soufre (S), et X étant de l'oxygène (O) ou de l'azote (N).
