Raman spectra of 15 wt% rGO/PI (a) and 15 wt% NH2-rGO/PI (b) thermally conductive composite films with laser power of 1.0 mW. Raman spectra of 15 wt% rGO/PI and 15 wt% NH2-rGO/PI thermally conductive composite films with increasing laser power (c). Relationship between Raman peak position of the C-N-C group of 15 wt% rGO/PI and 15 wt% NH2-rGO/PI thermally conductive composite films vs. laser power (d).
