Scalable ambient-dried aramid aerogel fibers with hierarchical networks for ultrahigh toughness and thermal insulation
Abstract
, water or citric acid) during solvent exchange is therefore essential to strengthen hydrogen bonding and stabilize ANF networks against capillary collapse. Furthermore, spatial heterogeneity in solvent composition, arising from proton-donor-induced solvent-solvent phase separation, creates a hierarchical pore architecture that enables multimodal mechanical energy dissipation, yielding simultaneously high tensile strength (>19.7 MPa) and unprecedented stretchability (>82%). The aerogel fiber-based textiles exhibit outstanding thermal insulation and resilience across cryogenic to high temperatures, offering a scalable pathway toward next-generation thermal-protective and impact-resistant aerogel textiles.
