Periodic Report Summary 1 - HIGRAPHEN (Hierarchical Functionalization of Graphene for Multiple device fabrication)

HIGRAPHENE project is based on the application of layer-by-layer (LbL) technology for the development of a versatile and generic procedure for the fabrication of hybrid devices involving graphene oxide and materials of a different nature such as polymeric, organic, and inorganic entities.
HIGRAPHENE aims to achieve the organization and integration of graphene sheets with heterogeneous components of different sizes and compositions into higher level structures/assemblies and devices. Components include polyelectrolytes, conductive polymers, magnetic nanoparticles, nanorods and quantum dots.
The development of new design principles and methods to control tunable dimension at the nanoscale, structure and property complexity of graphene. HIGRAPHENE aims to integrate, graphene, with inorganic particles and polymeric and organic species to develop building blocks for assembly and to understand the principles underlying their interaction that are fundamental to control graphene assembly and integration in devices. During the first years of the project work has focused on the synthesis of different nanomaterials i.e. ZnSe quantum dots, magnetic nanoparticle, and electroactive polymers like polyaminobenzylamines (PABA). These have been integrated into LbL films with multiple components and including graphene oxide. A novel methodology for the fabrication of multifunctional films has been developed based on the supramolecular interactions between phosphate molecules and polycations with primary amines, which can be used to entrap grapheme oxide. Additionally, capsules based on graphene oxide have been prepared on the basis of Layer by Layer films assembled on red blood cells. The optical and electronic properties of the fabricated materials and assemblies are being studied as well as their mechanical stability and permeability to small molecules and ions; their performance in devices as electrodes, their stability in aggressive media and their protective properties against corrosion in appropriate environments will also be tested
HIGRAPHEN will integrate the graphene assemblies into macroscopic anticorrosive coatings and devices for opto electronic applications and energy conversion. A main objective in HIGRAPHENE is to achieve supercapacitor electrodes on the basis of graphene assembly. The project aimsenerate a versatile platform for the nanoscale functional devices on the basis of GO that will contribute towards industrialisation of new energy and material efficient products and innovative processes.
To achieve these goals a strong international partnership has been built among European and Latinoamerican research groups with complementary expertises in Chemistry, Physics and Material Science. From the European side the group at CIC biomaGUNE, Spain, provides expertise in self assembly and material characterization while the group at CNRS has expertise on the synthesis of nanomaterials. The non European partners bring to HIGRAPHENE expertise in graphene chemistry, the group from CIQA in Mexico; in physics of magnetic materials and devices, the group from FUB in Brasil; and in electrochemistry, he groups at INIFTA in Argentina.
The scientific activities of HIGRAPHEN will be based on the exchange of Early Stage Researchers and Experience Researchers between the European Institutions on one side and the non European Institutions on the other side. In parallel to the scientific work extensive training activities are planned for the exchanged scientists.
