Nanofiber Aerogels

Vapor phase synthesis of metal–organic frameworks on a nanofibrous aerogel creates enhanced functionality

“…[35][36][37][38] NFA fabrication via freeze-drying of a dispersion of short electrospun nanobers in a non-solvent produces a brous entanglement featuring a bimodal distribution of primary (4-7 mm wide) and secondary pores (40-60 mm diameter). 34,39 Compared to the laborious and expensive synthesis of conventional aerogels, this efficient method has allowed researchers to broaden the landscape of NFAs' functionality. Among hybrid NFAs, thermally treated cellulose diacetate (CDA)-silica has received considerable attention for its excellent thermal and mechanical stability, sustainability, exibility, formability, and hierarchical porosity.…”
