Wide-angle X-ray diffraction profiles of (a) a 10 wt% blend of solution prepared crystalline Co nanoparticles in the C16-containing homopolymer, the 200 °C-treated (b) BCP and (c) homopolymer (identical to those shown in Fig. 3), and the 600 °C-pyrolyzed samples of the (d) BCP and (e) homopolymer, which removes all the organic ligands and allows the Co present to crystallize.
