A synergistic strategy for fabricating an ultralight and thermal insulating aramid nanofiber/polyimide aerogel

A synergistic strategy was proposed to fabricate an ultralight aramid nanofiber/polyimide (ANF/PI) composite aerogel (5.18 mg cm⁻³), which was highly compressible and low thermal conductivity (28.6 ± 0.53 mW (m K)⁻¹).
