Broadly speaking, a nanomaterial is one with one of the three dimensions of the grains or particles, which may take the form of crystal, amorphous material, quasi-crystal or interface layer structure, smaller than 100nm.

As early as 20 years ago, the nano-particles started to be introduced into the wet end retention system in papermaking, with a good effect.
