Abstract: A method of making an aerogel is described. The method can include obtaining a solution comprising polyamic acid and an imidazole, adding a dehydrating agent to the solution in an amount where the molar ratio of the imidazole to the dehydrating agent is 0.17:1 to 2.8:1 and reacting the solution at room temperature to 100° C. to produce a polymer matrix gel comprising a polyamic amide, and drying the polymer matrix gel to form an aerogel comprising an open-cell structured polymer matrix that includes 5 wt. % to 50 wt. % of the polyamic amide based on the total weight of the polymer aerogel.
