Gaining a momentum from newly emerging properties of nanomaterials the further enhancement and integration of various functionalities have been made possible. Also, it became apparent that interaction between nano-objects can provide additional synergy capable of yielding new or significantly improved properties. This particularly applies to the surfaces and interfaces of nanomaterials where the intimate contact between components amplifies possible contributions of interfacial interactions. Since this aspect of interaction-property relation in many nanocomposites is still insufficiently explored, it is of interest to identify to what extent the properties emerge as a result of interaction-based synergy or a co-action of individual components. To address these aspects, we have investigated a nanocomposite of graphene oxide (GO) and 12-tungstophosporic acid (WPA) – a combination of materials that are known for the rich “portfolio” of properties. In the talk the novel findings will be pr...esented that contribute to better the understanding of interactions between nano-objects and how they contribute to novel properties. The results are showing how simple temperature treatment and weight ratio of components is influencing the evolution of surface, structural properties and charge storage properties – all closely connected to interactions between components. Finally, the implications on synthetic approaches and fine-tuning of the functionality of GO/WPA nanocomposites will be discussed from the perspective of the obtained results.
