Abstract
In recent years, graphene oxide (GO) has been widely explored in many applications due to its exceptional properties. GO combined with polymeric materials offers the opportunity to develop novel functional and eco-friendly materials for the production of membranes and films. In this work, we report the fabrication of membranes based on GO and Nafion (N) colloids with different concentrations deposited on carbon paper (CP) by vacuum filtration technique. The morphological and structural characterization of the membranes was conducted by scanning electron microscopy and X-ray diffraction methods, respectively. To quantify the retention of GO/N colloids on the CP surface and bulk, UV-Vis optical spectrophotometry was carried out before and after the filtration process. UV-Vis spectra demonstrated total retention of GO/N colloids on the complete structure of the CP, which was also confirmed by energy dispersive X-ray spectrometry analysis.
