In the theoretical model colloidal particles considered as hard spheres and polymers are described using a form factor from Edwards-Flory mean field theory capturing self avoiding walk correlations. To find the polymer chain deformations close to the colloid surface the modified-Percus-Yevick (mPY) closure is implemented. Keeping the colloidal particle volume fraction low and varying the polymer concentration from infinitely dilute to semidilute we investigated the effect of the excluded volume interaction between the polymer monomers on the depletion layer and the induced interaction between the particles. Using numerical solutions of the PRISM-mPY equations the thermodynamic consistency is achieved, the radial distribution functions and second virial coefficient among the colloidal particles are investigated. At the end our theoretical prediction are compared with the existing results from the field theoretical approach in extreme limits and the experimental data.</dcterms:abstract> <dcterms:title>Excluded Volume Effects in the Depletion Attraction between Nanoparticles</dcterms:title> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:57:27Z</dc:date> <dcterms:issued>2009</dcterms:issued> <dc:contributor>Naderian, Maryam</dc:contributor> <dc:creator>Naderian, Maryam</dc:creator> </rdf:Description> </rdf:RDF>
