Ternary conducting polymer-based composite

A 128 X 64 X 16 finite element model in three dimensions was established to investigate the composition profile the physical dimensions of the slab before nondimensionaUzation are listed in Table 15.4. The numerical simulation was conducted based on the experimental conditions. Some of the parameters were directly imported from the experimental condition, while some - such as the gradient energy coefficient and mobility - were difficult to measure. Those parameter values which were not directly obtainable were first estimated via the theories described in Section 15.4.2, and then benchmarked in the numerical simulation with the experimental results. For phase separation in a polymer-polymer-solvent ternary system, the solubility of the polymers in the solvent is much greater than that of the polymers in each other [94]. Consequently, the interaction parameters between the solvent and two polymers were set as 0, and the interaction parameter between two polymers can be estimated with the following equation [33] ...
