The formation of precursor-‍derived nano-‍ensembles and their direct incorporation in a matrix are the subject of this topic. The resulting systems offer the generation of compositional gradient microstructures and tailored mechanical and electrical properties.
Such composites may form a novel group of molecularly designed functional materials based on the integration of, e.g., individual nanowires and nanotubes into addressable structures. The main tasks are to determine the optimum thermodynamic and kinetic conditions for the related microprocesses and to evaluate the mechanical and electrical properties of the resulting composite materials.
The main emphasis of current research is on the growth of specific nanowires, nanotubes and nanorods with precisely defined ordering structure and morphology. In addition, multiwall nanotube wires offer a great potential for a new class of microcomposite materials with significantly increased toughness compared to brittle matrix materials. Recently, work was performed to transfer the superior mechanical properties of nanotubes into ceramic matrices by dispersion in the green body and subsequent sintering or by in situ formation during firing in a carbon-containing methane atmosphere.
