| Outline of Annual Research Achievements |
The main objectives of the JSPS Kakenhi C project were to associate different colloids: micelles formed by nonionic surfactants, metal clusters and metal oxide nanosheets to graphene oxides and understand the different colloidal assemblies mainly driven by entropic effects. Beyond the fundamental interests of this research project about the understanding of the driving forces leading to the stabilization of the colloidal edifices and possible formation of hierarchical assemblies, GO was successfully used as a template system or supporting phase for the preparation of mesoporous materials and functional materials through their association / combination with metal clusters and metal oxide nanosheets for bactericide and electrochemical applications respectively
