Morphology Predictio n of Tern ary Blend s and Their Nanocomposites via Thermod ynamic A pproach

The properties of ternary bl ends are controlled by their morph ology, so it is necessa ry to predict it. Hobbs et al. [۱] u sed Harkin’s spreading coefficient concept to predict the phase morph ology of different tern ary blends. For a ternary system with A as the continues phase and B and C as th e dispersed phases, the spreading coefficients λB Cand λCB are defined as:(...)whereƴij is the int erfacial tension between i and j phases. A positive value of λBC and ne gative value of λCB will lead to encapsulation of C phase by the B ph ase. If λBC and λCB are both negative, two minor components form sep arate disper sed phases. In the case, both λCB and λBC are negative and λAC is positiv e one phase will partial ly encapsulate the other phase.
