Abstract: Described herein are insulating structures that include at least one microporous layer including a plurality of pores, a porous layer adjacent to the microporous layer, and a monolithic aerogel structure extending through the plurality of pores of the microporous layer and through at least part of the porous layer. The microporous layer filters aerogel dust from cracked or damaged aerogel within the scaffold, slowing or preventing loss of dust from the insulating structures.

Abstract: The present invention provides aerogel materials based on imidazoles and polyimidazoles. The polyimidazole based aerogel materials can be thermally stable up to 500° C. or more, and can be carbonized to produce a carbon aerogel having a char yield of 60% or more, specifically 70% or more. The present invention also provides methods of producing polyimidazole based aerogel materials by reacting at least one monomer in a suitable solvent to form a polybenzimidazole gel precursor solution, casting the polybenzimidazole gel precursor solution into a fiber reinforcement phase, allowing the at least one gel precursor in the precursor solution to transition into a gel material, and drying the gel materials to remove at least a portion of the solvent, to obtain an polybenzimidazole-based aerogel material.
