“…Two series of fullerenols have been used [5,6]. The first group of the samples has included iron based endofullerenols Fe@C 60 (OH) X (X ~ 30) (Fig.1) prepared by the process of hydroxylation of Fe@C 60 endofullerenes synthesized in electric-arc in inert atmosphere (helium) by the evaporation of composite electrodes (mixture of graphite and iron phthalocyanine pyrolysate).…”

It was observed a fractal-type fullerenols' ordering at the scale of correlation radii ~ 10-20 nm when molecules with iron atoms are integrated into branched structures at low concentrations (C ≤ 1 % wt.) and organized into globular aggregates at higher amounts (C > 1 % wt.). On the other hand, for Lanthanides captured in carbon cages the supramolecular structures are mostly globular and have larger gyration radii ~ 30 nm. They demonstrated a good stability in acidic (pH ~ 3) and neutral (pH ~ 7) media that is important for forthcoming medical applications.

“…Endohedral fullerene C 60 with incapsulated iron atom (Fe@C 60 ) has been recently obtained [14]. The Fe@C 60 nanoparticles have been used as a filler of the poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) matrix for membrane applications.…”

Impact of Endometallofullerene on P84 Copolyimide Transport and Thermomechanical Properties

Novel polymer composite materials, including unique nanoparticles, contribute to the progress of modern technologies. In this work, the endohedral fullerene C60 with incapsulated iron atom (endometallofullerene Fe@C60) is used for modification of P84 copolyimide. The impact of 0.1, 0.5, and 1 wt % endometallofullerene on the structure and physicochemical properties of polymer films is studied through scanning electron microscopy, thermogravimetric analysis, and thermomechanical tests. Transport properties are estimated through sorption and pervaporation techniques toward methanol and methyl acetate mixture. The inclusion of endometallofullerene into the copolyimide matrix improves membrane permeability and selectivity in the separation of methanol—methyl acetate mixtures. The maximal effect is achieved with a composite containing 0.5 wt % Fe@C60. The developed composites are effective for energy and resource saving purification of methyl acetate by pervaporation.
