Polystyrene Microstructured Foams Formed by Thermally Induced Phase Separation from Cyclohexanol Solution

Popis výsledku v původním jazyce

The thermally induced phase separation can be used to prepare materials of various micro-structured morphologies that define their applications. In this work, foams formed from a polystyrene-cyclohexanol solution are prepared, characterized, and modeled. To obtain a reliable thermodynamic description, cloud points are determined by an in-house fabricated thermooptical device. The Flory-Huggins lattice model combined with Hansen solubility theory is employed as input to the Cahn-Hilliard model of phase separation dynamics. The previously reported model is extended by incorporating polar interactions. The resulting experimental and predicted morphologies are compared and good prediction capabilities of the model regarding the resulting morphology and its characteristics are obtained. The experimental and modeling work extends the knowledge of the mechanism and the kinetics of foam morphology evolution for thermal and sound insulation applications.
