Figure 2. Dispersibility of Si and CNTs. (A) Optical images of CNTs and PAM-g-CNTs dispersed in DI water. Micro-CT images of Si mixture with (B) CNTs and (C) PAM-g-CNTs; 3D laser scanned images of Si electrodes with (D) CNTs and (E) PAM-g-CNTs. CNTs: Carbon nanotubes; PAM-g-CNTs: polyacrylamide-grafted CNTs; DI: deionized; 3D: three-dimensional.
