“…The Cahn-Hilliard model has been used to describe various morphology evolution processes including phase separation and inversion primarily in binary systems. [23][24][25] Vonka and Kosek 26 modeled the morphology evolution of hetero-phase polymers with a modified Cahn-Hilliard model that undergoes phase separation and inversion during their formation. High impact polystyrene (HIPS) was selected with double-emulsion morphology, consisting of the continuous PS phase with dispersed micron-sized polybutadiene (PB) particles containing submicron occlusions of the partially grafted copolymer (PB-g-PS).…”

Experimental and theoretical analysis of the phase morphology and electrical conductivity of a carbon black (CB)‐filled polypropylene /poly(methyl methacrylate) /ethylene acrylic acid copolymer ternary system were compared. The Cahn‐Hilliard theory was used to model and predict the phase morphology and electrical conductivity as a function of the constituents' characteristics of the ternary system. A method for generating statistically representative microstructures of a co‐continuous ternary polymer system and a numerical method for calculating the resultant electrical conductivity of these ternary polymer systems are presented. Excellent agreement between numerically calculated and experimentally measured results was observed. The developed analytical and numerical models were able to successfully predict the electrical percolation threshold with that of ternary polymer composites containing CB as a conductive medium with minimal experimental input. The combination of experimental and numerical results presented suggests the optimization of the conductive minor phase includes having a conductivity beyond the critical percolation threshold, is at least three orders of magnitude greater than either of the two nonconductive phases, and has a lower viscosity than the other two major phases in order to maximize the phase separation kinetics. © 2017 Wiley Periodicals, Inc.
