Abstract

The present disclosure generally relates to a process for manufacturing a processable dried cellulose nanomaterial using a co-solvent of tert-butyl alcohol (TBA), of which unique physical/chemical properties enable facile modification/derivatization. This present disclosure also relates to materials and process of generating of superhydrophobic surface coating using hydrophobic carboxylic acid modified cellulose nanofibers. Both the processes and the products thereof are within the scope of this disclosure.
