The influence of physical and chemical linkage on the properties of nanocomposites [PDF]

open access: yes, 2005
It has been shown by several groups that the mechanical and electrical behavior of composites changes quite substantially, and often beneficially, when the filler particle size is less than 100 nm in diameter.
