  • What are the differences between Nano-fillers and Nanoparticules?

A tiny inorganic particle used in advanced composites. Nanofillers improve the appearance and mechanical properties of composite parts. Ultrafine particles, or nanoparticles, are between 1 and 100 nanometers in size. The reason for this double name of the same object is that, during the 1970-80s, when the first thorough fundamental studies with "nanoparticles" were underway in the USA (by Granqvist and Buhrman)and Japan, (within an ERATO Project) they were called "ultrafine particles" (UFP). However, during the 1990s before the National Nanotechnology Initiative was launched in the USA, the new name, "nanoparticle," had become fashionable (see, for example the same senior author's paper 20 years later addressing the same issue, lognormal distribution of sizes). Nanoparticles may or may not exhibit size-related properties that differ significantly from those observed in fine particles or bulk materials.[5][6] Although the size of most molecules would fit into the above outline, individual molecules are usually not referred to as nanoparticles.
