In this work, we have studied the affinity of pure C₆₀ fullerenes with water. Although C₆₀ have always been known as hydrophobic particles, we show that this characteristic does not remain when contact between C₆₀ and H₂O is forced by mechanical stirring. Light scattering measurements and transmission electron microscopy observations revealed the presence of C₆₀ aggregates remaining stable in water after stirring, with a large nanometric size range. Water adsorption/desorption isotherms, confirmed the hydrophilic character of these nano‐clusters, resulting form hydration of the initial hydrophobic C₆₀.
