The effect of small amounts of nanoparticles on the melt-state linear viscoelastic behaviouris investigated for different polymer-nanoparticles model systems characterized bypoor polymer-particles interactions and low particle contents.contents. The drastic increase of therheological properties with respect to the matrices is related to the formation of afiller network above a critical particles volume fraction. Once formed, thefiller network exhibits an elastic feature that mixes with the intrinsic viscoelastic response ofthe polymer matrix, resulting in a complex Φ- and ω-dependent viscoelastic response of thenanocomposite. However, we show that the contributions of filler networkand suspending medium can be decoupled due to the weak polymer-particle interactionsand the differences in temporal relaxation scales. The adopted approach is validatedthrough the building of a master curve of the moduli, which reflects the scaling of theelasticity of composites along the viscosity of the suspending medium. The two-phasemodel well works irrespective of the structure of the filler network, making evident thestrict interrelationships between the structure, both on nano- and micro-scale, and the melt-state behaviour of the studied PNCs
