Classification of nanomaterials.

Categories of nanomaterials	Description	References
Nanoparticles	Submicron or even ultramicron size particles obtainable as high performance radiant resistant materials, magnetic materials, solar battery materials, packaging materials, and magnetic fluid materials	[11, 12]
Nanotubes and nanofibers	Nanometer size long linear material, optical materials, micro conductors, microfibers, nanotubes of PEEK, PET, and PTFE	[8]
Nanofilm	Films utilized as gas catalyst materials	[18]
Nanoblock	Nanometer crystalline materials produced by substantial accuracy, developing controlled crystallization or nanoparticles	[19]
Nanocomposites	Composite nanomaterials, which use nanosize reinforcements instead of conventional fibers or particulates	[15]
Nanocrystalline solids	Polycrystals with the size of 1 to 10 nm and 50% or more of solid consists of inherent interface between crystals and different orientations. The clusters that formed through homogenous nucleation and grow by coalescence and incorporation of atoms.	[16]
