“…118 On this point, it must be said that browsing the web one encounters classifications which can be misleading, often use different languages and are even discordant with each other (this depends very much on the applications and philosophy for which they are adopted). 119 Here, the reviewed works are classified into four categories on the base of nanofiller dimensionality: three-dimensional (3D), that is particles having three nanometric dimensions such as nanosilica, CB; two-dimensional (2D), that is sheets, platelets, layers having one dimension in the nanometer range, such as layered silicates, layered double hydroxides, graphene and graphene oxide nanoplatelets; one-dimensional AUTHOR(S) (1D), that is tubes, rods, wires, fibers having two dimensions in the nanoscale, such as carbon nanofibers, carbon nanotubes, cellulose whiskers, gold nanowires; zero-dimensional (0D), that is ultra-small size nanostructures with spherical or quasi-spherical geometry, such as fullerenes, quantum dots, polyhedral oligomeric silsesquioxanes, gold nanoparticles.…”
