The incorporation into PU foams of different types and concentrations of nanosized functional particles, both platelet-like such as nanoclays or graphene, fibrous-like such as carbon nanotubes and nanofibers, or even spherical-like such as nanosilica, has been shown to have a significant effect in the structure and physical properties of the resulting materials, considerably expanding the already wide range of possible applications of these lightweight materials.
