On the wetting of polyethylene terephthalate substrates with multicomponent graphene oxide dispersions

In this work, we investigate wetting properties of polymer polyethylene terephthalate (PET) substrates with graphene oxide multicomponent dispersions. Overcoming poor wettability polymer substrates like PET, promising for flexible electronics applications, with commercially available water graphene oxide suspensions is proposed to solve by adding organic components. We used dimethylacetamide (DMA) and thinner for lacquer paints (LT) to successfully show the decrease of wetting angle. Moreover, we showed stability of multicomponent dispersion with DMA within more than 6 months and LT within more than several weeks and also found out that drying time of droplets of mixed dispersions with different additives may vary more than 15 times that is important for choice of the preferred deposition method.
