Abstract

Raman spectra of composite aerogels of polytetrafluoroethylene and graphene oxide (reduced grahpene oxide) (PTFE–GO (RGO)) are obtained and described. Five peaks (two Gaussians and three pseudo-Voigt functions) are used to describe spectra in the region of 800–2100 cm−1. Thermal and hydrazine reduction are found to affect the positions of individual components in the Raman spectra differently. Any of the treatments used in this work (reduction by hydrazine with subsequent annealing at 250 or 370°C) applied to PTFE–GO (RGO) composite aerogel reduces the average size of graphene crystallites.
