제목 Estimation of the interfacial energy between heterogenous polymers based on the spontaneous induction of morphological transformation of kinetically stable particles
초록 Measurement of the interfacial surface energy between two heterogeneous polymers is not trivial. In this work, We propose a method for predicting the interfacial energy between heterogeneous polymers by converting a kinetically stable particle (KSP) to a thermodynamically stable particle (TSP) and comparing the result with the surface free energy calculation. KSP can be fabricated using piezo-driven inkjet technology; the rapid evaporation of a volatile solvent including the generated heterogeneous polymer droplets in the air leads to the instantaneous solidification before forming a thermodynamically stable structure. KSP can be induced to have a thermodynamically stable morphology by swelling under an appropriate solvent environment. Using the surface energy calculation method, a library of various structures according to the change in the solid-solid interface energy can be produced, and the solid-solid interface energy value can be found by comparing the experimental results.
