Abstract

A systematic study has been carried out of the conditions for obtaining stable aqueous dispersions of fullerene C60 by ultrasonic treatment in solutions of dermatologically mild nonionic surfactants. The obtained dispersions were used to modify gels based on lightly crosslinked polyacrylic acid. A study of the rheological properties of the gels has shown that the addition of C60 reduces the viscosity and yield stress of the gels by a factor of 1.7. The electrical conductivity of the gel systems increased by 2.2–2.5 times compared to the base gel. It has been found that the modified gels provide a more intense release of diclofenac sodium during electrophoresis. In addition, the introduction of fullerene enhances the antioxidant activity of the gel by 30%.
