Spectroscopic and electrical analysis of graphene composites.
a, A typical cross-section SEM image of 3.8 wt% G-ABS composite’s revealed partially incorporated dangling graphene sheets. b, Electrical conductivity (σc) of G-ABS composites as a function of graphene loading. Inset is the four-probe schematic setup used in the σc measurement. c, Representive Raman spectra in prepared GO, rGO, ABS and G-ABS samples. d, UV-vis spectra of separated samples dispersed in aqueous solutions, including GO, GO-ABS, G-ABS, rGO.
