実験手順

A suspension with the desired amount of nanocrystalline cellulose (2 grams in 100 grains methanol; 2 wt %) was solvent exchanged to acetone and then to dry toluene by several successive centrifugations and redispersions. Sonication was performed after each solvent exchange step. The suspension was transferred to a 3-neck round bottom flask and an excess of 2H,2H,3H,3H-perfluoroundecanoic acid (available from SynQuest Laboratories) was added to the stirring suspension followed by a catalytic amount of p-toluenesulfonic acid. The surface modification of the cellulose nanostructures were conducted at 105° C. for up to 24 hours. Following surface treatment, the material was purified and dried as in Example 1.
