EPR spectra of fullerene, FS, FB, and composites Phenylon C-2/FS, FB. a. 1—initial samples of the fullerene C60, 2—fullerene soot (FS), 3—fullerene black (FB) at room temperature. Dashed lines are the calculated signals (Table 1). ν = 9350 MHz. The insert: EPR spectrum of the fullerene black at T = 30 K. b. Composites Phenylon C-2 + 3% fillers, notably: 1—fullerene C60, 2—fullerene soot (FS), 3—fullerene black (FB). The supplementary broad line on the spectrum (1) belongs to Phenylon C-2. ν = 9375 MHz, gain = ×5. The insert: The EPR spectrum of the composite PhC-2 + 3% FS at T = 30 K. Dashed lines—fitting (Table 1)
