a Compressive cycle curve of AP-23 organogel. b Tensile cycle curve of AP-23 organogel. c Compressive stress-strain curves of AP-23 organogel, hydrogel, and aerogels. d Tensile stress-strain curves of AP-23 organogel, hydrogel, and aerogels. e Compressive stress-strain curves of AP-17, AP-19, AP-23, AP-25, AP-27 aerogels. f Tensile stress-strain curves of AP-17, AP-19, AP-23, AP-25, AP-27 aerogels. g Photographs of AP-23 aerogels under compression and tension: AP-23 aerogel with sizes of 0.5 × 0.5 × 0.5 cm³ bearing 1 kg loading; AP-23 aerogel plate lifting 5 kg water. h Compressive stress-strain curves and SEM images (insert) of AP aerogels with and without freeze-thawing process. i Toughness and specific tensile modulus of AP aerogels with different densities, as compared with other high-strength polymeric aerogels including composite nanofiber aerogels (CNA), becterial cellulose (BC) aerogels, polyimide(PI) aerogels, and chitin/chitosan aerogels. The toughness was calculated by integrating the tensile stress-strain curves from various materials (Supplementary Table 1).
