Abstract

In this work, graphene oxide-titanium oxide (GO-TiO2) nanocomposite was successfully produced via ultrasonication process. For coating process, spin coating (SC), dip coating (DC) and spray coating methods were used. The synthesized nanocomposite and surfaces were characterized by optical microscope, SEM, EDX, FTIR, XRD, four-probe conductivity, water contact angle.
As result of experiments, while spin coating provides thinner coating, a thicker and higher water contact angle surface was formed under the optimum condition of dip coating. XRD, four-probe conductivity results revealed partial formation of reduced graphene oxide within the composite structure. Water contact angle results showed that the best result regarding stability of droplet shape was on the spin coated surface. On the other hand, it was observed that deionized water test liquid droplet on the dip coated surfaces stabilized relatively slower but provided a much higher water contact angle.
