From: Explosive percolation yields highly-conductive polymer nanocomposites

A–H Fitted XPS data showing the C1s (A–D) and O1s (E–H) features. The unreduced (A, C, E, G) and reduced (B, D, F, H) samples are investigated for the pristine latex polymer and 2 wt% GO composites. I FTIR spectra for both unreduced and reduced 2 wt% composites. Mode assignments are indicated, with those emerging as a result of the reduction process highlighted in orange.
