Analysis of Defect Recovery in Reduced Graphene Oxide and Its Application as a Heater for Self-Healing Polymers

“…In our previous reports, we revealed that reactions leading to ALD of Pt can take place only on chemically active defect sites, such as grain boundaries, and that no chemically active site on the ideal graphene surface is composed of sp 2 hybridized bonds . Compared to the few-layered CVD-grown graphene, RGO seems to be composed of multilayered structures owing to the spin-coating of the RGO solution; − however, Pt was randomly formed during the ALD on the surface, and not along the edge of each RGO flake (see Figure S3 of Supporting Information). In Figure b,c, the C 1 s high-resolution (HR) XPS patterns of the RGO and CVD-grown graphene are deconvoluted, with the deconvoluted peaks assigned to the CC (284.6 eV), C–C (285.4 eV), C–O (286.4 eV), C–O–C (287.5 eV), CO (288.6 eV), and OC–O (289.4 eV) moieties. , Herein, the C–O peak intensity of the RGO relative to those of CC and C–C appears to be much higher than that of the CVD-grown graphene (see Figure S4 of Supporting Information for the peak areas).…”

“…The vaporized MeCpPtMe 3 molecules were transported into the reaction chamber by the N 2 carrier gas flowing at the rate of 30 sccm for 2 s. The unreacted Pt precursors and byproducts were purged by the N 2 gas for 15 s and exposed to the O 2 counter reactant for 4 s. This was followed by N 2 purging for 30 s to eliminate the ligands of the chemisorbed Pt precursors and evacuate the byproducts. Additional information on the Pt ALD process can be found in our previous paper . The number of ALD cycles was systematically varied from 20 to 150.…”
