Title: | Assessment of the Tumbling-Snake Model against Linear and Nonlinear Rheological Data of Bidisperse Polymer Blends | Authors: | Stephanou, Pavlos Kröger, Martin |
Major Field of Science: | Natural Sciences | Field Category: | Chemical Sciences | Keywords: | Polymer melt;Stochastic differential equation;Link tension coefficient;Entanglements;Bidisperse systems | Issue Date: | 20-Feb-2019 | Source: | Polymers, 2019, Volume 11, Issue 2, Article Number 376 | Journal: | Polymers | Abstract: | We have recently solved the tumbling-snake model for concentrated polymer solutions and entangled melts in the academic case of a monodisperse sample. Here, we extend these studies and provide the stationary solutions of the tumbling-snake model both analytically, for small shear rates, and via Brownian dynamics simulations, for a bidisperse sample over a wide range of shear rates and model parameters. We further show that the tumbling-snake model bears the necessary capacity to compare well with available linear and non-linear rheological data for bidisperse systems. This capacity is added to the already documented ability of the model to accurately predict the shear rheology of monodisperse systems. | URI: | https://hdl.handle.net/20.500.14279/13707 | ISSN: | 20734360 | DOI: | 10.3390/polym11020376 | Rights: | © 2019 by the authors. | Type: | Article | Affiliation : | Novamechanics Ltd.
