Sustainable, Flexible, and Superhydrophobic Functionalized Cellulose Aerogel for Selective and Versatile Oil/Water Separation

Aerogels, as ultralight three-dimensional (3D) highly porous materials, show great superiority in oil and organic pollutant cleanup. Notably, biomass aerogels have also attracted wide interest due to the advantages of huge reserves, low cost, renewability, biodegradation, and nontoxicity to the environment. Herein, a sustainable, flexible, and superhydrophobic functionalized cellulose aerogel, copper nanoparticles-coated cellulose aerogel...
