Polymer Adsorbed Layer and Available Surface Area of Fillers in the Nanocomposites

Polymer-filler interactions [1-3] tend to the adsorption of polymer chains on the filler surfaces. The adsorbed polymer chains have different properties compared to the free polymers[4]. The filler-fillerinteractions change the structure and the available surfaces area of the fillers in the composites [5-7]. The properties of the nanocompositesare changes with the amounts adsorbed polymers. The adsorbed polymer is related to the adsorbed layer thickness and availablesurface area of the nano-particles. Hence, in this research relation are presented to estimate those parameters from the density of the nanocomposites. These relations are based on the theory of the composites mixing roles.
