Natural layered silicates have been established as nanofillers with a broad range of potential applications. Synthetic layered silicates (second generation) with aspect ratios of up to 20000 and lateral diameters larger than 2 µm allow for a further quantum leap in relevant material properties. Moreover, novel phenomena not to be observed for natural clays like significant improvement of toughness may be realized. With high filler contents efficient high barriers films can be fabricated even for highly diffusive gases like H2. One remaining current challenge is the realization of multifunctional modes of action like concomitant improvement of fracture toughness and flame retardancy.
