چکیده

We extend the linear “stick-slip” models of Doi-Edwards and Johnson-Stacer to nonlinear tube reptation models. We then show that such models, when combined with probabilistic formulations allowing distributions of relaxation times, provide a good description of dynamic experiments with highly filled rubber in tensile deformations. A connection to other applications including dielectric polarization and reptation in other viscoelastic materials (e.g., living tissue) is noted.

A Reptation Model for Magnetic Materials

Reptation, or accommodation, is manifested in ferromagnetic materials in a variety of operating regimes and hence must be incorporated in models used for comprehensive material characterization or model-based control design. Because the microscopic mechanisms which cause reptation are complex, we characterize the effect in a phenomenological macroscopic manner within the context of a homogenize...

Surfactant mobility in nanoporous glass films.

Polymer molecules when physically confined at nanometer length scales diffuse nonclassically and very differently depending on their molecular weight and the nature of the confinement. Long polymers that exhibit "snakelike" reptation based mobility in melts may diffuse faster in confined nanometer sized cylinders with pore diameter d approximately 15 nm, and short polymers subject to Rouse dyna...

Disentanglement and Reptation During Dissolution of Rubbery Polymers

The dissolution mechanism of rubbery polymers was analyzed by dividing the penetrant concentration field into three regimes that delineate three distinctly different transport processes. The solvent penetration into the rubbery polymer was assumed to be Fickian. The mode of mobility of the polymer chains was shown to undergo a change a t a critical penetrant concentration expressed as a change ...

On the Importance of Chain Reptation in Models of Dissolution of Glassy Polymers

Polymer dissolution was described by chain reptation incorporated into penetrant transport. The penetrant concentration field was divided into three regimes which delineate three different transport processes. Solvent penetration through the polymer was modeled to occur as a consequence of a diffusional flux and an osmotic pressure contribution. Species momentum balances were written that coupl...

Simulations for Structural and Dynamic Properties of Dense Polymer Systems

Recent attempts to investigate the properties of dense and semidilute polymer systems are reviewed. Both molecular dynamics (MD) and Monte Carlo (MC) methods provide direct evidence for the reptation model and give a rather detailed picture of the motion of linear polymers at high density. Mapping the results onto various chemical polymers allow one to predict the time and length scale for the ...
