摘要
A polyvinylidene fluoride (PVDF) aerogel was fabricated by a phase inversion induced sol-gel process along with supercritical drying. The PVDF aerogel exhibited a hierarchical structure consisting of agglomerates and micron-size voids. The agglomerates consisted of nanoparticles and nanopores. The PVDF aerogel showed a water contact angle of 126° and was thermally stable up to 400 °C in aerial environment. The thermal conductivity of the PVDF aerogel was as low as 0.03602 W/(m·K). The PVDF aerogel is promisingly applied in thermal insulation under humid conditions and water treatment.
