Nanocomposites are polymer materials with several phase domains, in which at least one of these domains has a nanoscale structure. (e.g. through the use of nanoadditives such as nanofibres, nanotubes or other nanoscale particles).
The materials can already exhibit new chemical and physical properties through relatively low input concentrations of corresponding nanoadditives.
These properties depend strongly on the morphology and the interfacial properties of the composite materials. Therefore, in order to fully utilise and achieve the desired effects - such as electrical conductivity, enhancement of the barrier or modification of the rheological properties - an optimal distribution and bonding of the additives is necessary. This requires process-engineering and material-specific solutions (including adhesion promoters or synergistic combinations).
