Radius of gyration of polymers in melt with nanoparticles of radius $R_{\text{n}}=1,2$ normalized with its value in the bulk for polymer chains of $N=200$ and $N=100$ (inset) repeat units (monomers): (i) polymer melt (blue filled circles), (ii) nanocomposite: attractive monomer-nanoparticle ($R_{\text{n}}=2$) interactions (red filled circles), (iii) nanocomposite: repulsive monomer-nanoparticle ($R_{\text{n}}=2$) interactions (black filled diamonds), (iv) nanocomposite: attractive monomer-nanoparticle ($R_{\text{n}}=1$) interactions (red open circles), (v) nanocomposite: repulsive monomer-nanoparticle ($R_{\text{n}}=1$) interactions (black open diamonds). The black dashed line shows $R_{\text{g}}/R_{\text{g,0}}\propto {\left(1-\mathit{\varphi }\right)}^{-1/3}.$ (Color figure online) (Reprinted from [135]—Published by The Royal Society of Chemistry.)
