Τίτλος: | How the flow affects the phase behaviour and microstructure of polymer nanocomposites | Συγγραφείς: | Stephanou, Pavlos S. | Major Field of Science: | Engineering and Technology | Field Category: | Chemical Engineering | Ημερομηνία Έκδοσης: | 9-Φεβ-2015 | Πηγή: | Journal of Chemical Physics, 2015, vol. 142, no. 6 | Volume: | 142 | Issue: | 6 | Περιοδικό: | Journal of Chemical Physics | Περίληψη: | We address the issue of flow effects on the phase behaviour of polymer nanocomposite melts by making use of a recently reported Hamiltonian set of evolution equations developed on principles of non-equilibrium thermodynamics. To this end, we calculate the spinodal curve, by computing values for the nanoparticle radius as a function of the polymer radius-of-gyration for which the second derivative of the generalized free energy of the system becomes zero. Under equilibrium conditions, we recover the phase diagram predicted by Mackay et al. [Science 311, 1740 (2006)]. Under non-equilibrium conditions, we account for the extra terms in the free energy due to changes in the conformations of polymer chains by the shear flow. Overall, our model predicts that flow enhances miscibility, since the corresponding miscibility window opens up for non-zero shear rate values. | URI: | https://hdl.handle.net/20.500.14279/15821 | ISSN: | 00219606 | DOI: | 10.1063/1.4907363 | Rights: | © AIP Publishing LLC.
