The advantages of using dicarboxylic acid for the preparation of NCs are that (1) carboxyl groups are introduced on the surface of CNCs and CNFs, as ester group could have been formed by the reaction of dicarboxylic acids with cellulose [92]; (2) solid dicarboxylic acid (e.g., oxalate and maleic acid) is of low corrosion to equipment and could be fully recovered by using crystallization technology; (3) the resultant CNCs and CNFs are thermally stable which is beneficial for the manufacture of composite.
