In this work, the nanotechnology procedure was utilized to improve both the adhesion force and
surface properties of graphene oxide (GO) films. GO has been obtained in a powder form by oxidation
purified graphite using the modified Hummer’s technique. Different films of GO nanoparticles (NPs)
were deposited using several types of solvents distilled water, acetone, ethanol, dimethylformamide
(DMF) or ethylene glycol. The examination of structural and optical properties of GO films was studied
by XRD and UV–vis absorption spectroscopy. Moreover, electrical properties, surface roughness,
contact angle, adhesion force, wetting energy and spreading coefficient were investigated. It was
observed that the properties of the prepared films are influenced by the solvent type. The electrical
resistivity of films is highly dependent on the solvent type which exhibited the lowest value with
distilled water. Furthermore, GO film synthesized with distilled water has the best values of adhesion
force and average surface roughness (Ra) 143.4 mN/m and ~ 7.83 µm, respectively. These results
are mostly attributed to hydrophilic cites and GO NPs agglomeration in the surface of films and the
effects of their size leading to an expansion in the surface roughness.
