On the Solubility Parameter of C₆₀ and Higher Fullerenes

Abstract

The solubility parameter (δ _t) of C₆₀ and C₇₀ and higher fullerenes up to C₉₀ have been calculated according to the group increment approach proposed by Van Krevelen. The results have been compared with the Hansen solubility parameter. The differences in the calculation procedure and in the meaning of the Van Krevelen and Hansen solubility parameter have been presented and discussed. In particular, it has been found that the Van Krevelen method gives a slight lower value (δ _t  =  19.5 MPa^1/2) than the value calculated according to the Hansen approach. The solubility parameter shows a slow growth trend by increasing the sizes of fullerenes.
