Chemical modification of cellulose nanofibers with phthalimide air filter to adsorb carbon dioxide

The applications of renewable nanomaterial’s, such as cellulose nanofibers (CNFs), have recently been of great interest due to their unique properties, including high surface area, high aspect ratio, biodegradable, easy access and reactive hydroxyl groups on the surface. The purpose of this study wa...
