Quasi-liquid composites based on poly(ethylene terephthalate) films with fullerene and dichlorobenzene

Quasi-liquid composites based on poly(ethylene terephthalate) (PET) films with 9 wt% solution of the C₆₀ (70%) and C₇₀ (∼30%) fullerenes mixture in dichlorobenzene (DCB) have been obtained. It has been shown that PET swelling in the fullerene solution in DCB is accompanied by penetration of fullerene into the polymer structure, and PET films are deformed by the mechanism of intercrystallite crazing. As has been revealed by UV spectroscopy, fullerene incorporated into composite remains monomeric as in solution.
