Ultralight and highly flexible biopolymer aerogels, composed of biomimetic cellular
microstructures formed from cellulose nanofibers and silver nanowires, are assembled via a
convenient and facile freeze-casting method. The lamellar, honeycomb-like, and random
porous scaffolds are successfully achieved by adjusting freezing approaches to modulate
the relationships between microstructures and macroscopic mechanical and
electromagnetic interference (EMI) shielding performances. Combining the shielding …
