Subject particulate fillers

In another similar example nanocomposite was formed in a polyurethane matrix. Solvent soluble polyurethane had pyridine groups attached which formed complexes with metal salts. Films were then formed and subjected to a reducing agent in order to produce particulate metal filler. In this case the distribution of the filler which was formed was not uniform because the filler had tendency to aggregate (even though it was chemically attached to the matrix prior to the reduction). The following were factors controlling size and shape of these metal particles ... 

Particulate and fiber reinforced polymers are used in many fields of application, but mostly in areas where they are subjected to the effect of various external loads. Mechanical properties are strongly influenced by the presence of the filler or reinforcement and by all factors mentioned in the previous sections. The study and prediction of mechanical properties is very important in both research and development.
