Viscoelastic properties of polymer solutions.
In a concentrated polymer solution, the entanglement of long-chain molecules results in a transient network structure, to which may be attributed certain aspects of the viscoelastic behavior of such a system. A suitable mechanical model for representing this network as a first approximation is a retarded Maxwell element with one spring and two dashpots. Experimental measurements of mechanical p...
متن کاملMultiscale Modeling of Viscoelastic Properties of Polymer Nanocomposites
A methodology for simple multiscale modeling of mechanical properties of polymer nanocomposites has been developed. This methodology consists of three steps: (1) obtaining from molecular dynamics simulations the viscoelastic properties of the bulklike polymer and approximating the position-dependent shear modulus of the interfacial polymer on the basis of the polymer-bead mean-square displaceme...
متن کاملA review on melt-state viscoelastic properties of polymer nanocomposites.
The mixing of polymer matrices with nanoparticles to form composite materials has been an area of great research interest. The mechanical and rheological properties of such composite materials are directly related to the properties of the matrix polymer, the properties of the nano-filler, the strength and nature of the interfacial interactions between the polymer matrix and the filler, and fina...
متن کاملViscoelastic properties of confined polymer films measured via thermal wrinkling†
We present a new wrinkling-based measurement technique for quantifying the viscoelastic properties of confined polymer thin films. This approach utilizes real-time laser-light scattering to observe the kinetics of thermally-induced surface wrinkling, which evolves isothermally as a function of annealing time. Specifically, wrinkling is induced by applying a thermal stress to a polystyrene film ...
متن کاملViscoelastic Properties of Polymer Melts from Equilibrium Molecular Dynamics Simulations
Introduction. The dynamics of polymer chains are now generally very well understood in the pioneering frameworks of the Rouse model for short chains, and the reptation model for longer chains.1-5 While these theories yield well-known expressions for the variation of the diffusivity D and viscosity η with the chain length N, an open question is the chain length at which one crosses over from Rou...
