Chapter 7 β Application of Graphene composites: Raman Strain Sensors Figure 7.8: a, b) Optical image of few SLG in the exfoliated coatings. c, d) Transferred CVD graphene coatings. Wrinkles and damages were observed due to the transfer process. 7.3.1.2. Raman spectroscopy characterisation Composite coatings were prepared from both MC and in-house CVD-grown graphene. The schematics of the sample preparation were shown in section 4.2.2 and 4.2.3. The in situ Raman measurements were carried out on the graphene monolayer flakes as shown in the optical micrographs (Figure 7.8). Well-defined Raman spectra with a characteristic 2D band (around 2640 cm-1), G band (around 1580 cm-1) and D band (1350 cm-1) were obtained from both the MC and CVD graphene. Figure 7.9a shows the example flakes found in the composite system with increasing number of layers, with the πΌ2π·βπΌπΊ ratio greater than 3 for the SLG. The absence of a D band for the MC graphene reveals its high-quality.48 Figure 7.9b shows the Raman spectra of as-grown CVD graphene on Cu foil and in the coatings. πΌ2π·βπΌπΊ ratio was greater than 2 and the FWHM(2D) of ~25 cm-1. 209PDF Image | PRODUCTION AND APPLICATIONS OF GRAPHENE AND ITS COMPOSITES
