Abstract: The present disclosure provides a method of producing a aerogel comprising of reacting first monomer with a second monomer in a reaction solvent to form a composition comprising a precursor polymer; forming a gel; conducting a solvent exchange process on the gel such that the resulting gel comprises an exchange solvent that has a freezing point; cooling the gel to a temperature below the freezing point of the exchange solvent; and subjecting the cooled gel to vacuum conditions to obtain the aerogel.

Abstract: The present disclosure provides a method for producing an aerogel, the method comprising reacting at least one acid monomer with at least one diamino monomer in a first solvent under conditions appropriate to form a polyimide polymer; conducting a solvent exchange wherein the first solvent is exchanged for a second solvent, said second solvent having a freezing point, wherein said solvent exchange further comprises (1) submersing the polyimide polymer in the second solvent in a pressure vessel and (2) creating a high pressure environment inside the pressure vessel for a first period of time; cooling the polyimide polymer to a first temperature below the freezing point of the second solvent; and subjecting cooled polyimide polymer to a first vacuum for a second period of time at a second temperature.
