Properties of Amorphous Solids and Supercooled Liquids near the Glass Transition: Models for Liquids at Interfaces and in the Condensed Phase
EMSL Project ID
51165
Abstract
The aims of this proposal are to develop, implement, and execute innovative experimental approaches to measure the physical properties of amorphous solids and supercooled liquids near the glass transition temperature, Tg. These data will provide a stringent test for the various proposed theoretical models of liquid behavior and lead to a deeper fundamental understanding of the dynamical slowdown that occurs in supercooled liquids approaching the glass transition. Experimental measurements of the properties of supercooled liquids near Tg are requisite for understanding the behavior of glasses and amorphous solids. Unfortunately, many supercooled molecular liquids rapidly crystallize at temperatures far above their Tg, making such measurements difficult to nearly impossible. Alternative approaches to obtain experimental data in this temperature regime are needed. We anticipate that the data obtained in this proposal will be of sufficient accuracy and reproducibility so that direct comparison with theoretical models and calculations will be possible.
