WebFeb 22, 2024 · Nevertheless, the AFM images of graphene-modified asphalt before and after ageing [Fig. 7 (d)–(f)] show no significant change in the tubers, which indicates that the properties of the graphene-modified asphalt change little after ageing. During the ageing process, graphene sheets dispersed in asphalt can effectively inhibit the diffusion of ... WebThe AFM images of graphene film before and after PBASE modification are shown in Figure 3a and Figure 3b, respectively. The root mean square (RMS) surface roughness of graphene is extracted from an area of 2.5 × 2.5 μ m 2 (within the white dashed box in the AFM images in Figure 3 a,b).
