Gradiented sulfonation was performed for the surface modification of cellulose nanocrystals by conjugate addition with sodium vinyl sulfonate moieties. The self-assembly behaviors of the modified nanocrystals in the liquid state as suspensions and in the solid state as films were regulated by their surface chemistry and crystalline properties.
