Nanocellulose Aerogels Functionalized by Rapid Layer‐by‐Layer Assembly for High Charge Storage and Beyond

Step by step: A robust and rapid method for the layer-by-layer assembly of polymers and nanoparticles on strong and elastic aerogels has been developed. Thin films of biomolecules, conducting polymers, and carbon nanotubes were assembled, which resulted in aerogels with a number of functions, including a high charge-storage capacity.
