Abstract:

Vapor-deposited glasses of toluene and ethylbenzene have been characterized by in-situ AC chip-nanocalorimetry. We observed that vapor-deposited glasses have up to 4% lower heat capacities than the ordinary glass. The largest heat capacity decrease and the most kinetically stable glasses of toluene and ethylbenzene are observed in a range of deposition temperatures between 0.75 Tg and 0.96 Tg. In addition, AC nanocalorimetry was used to follow the isothermal transformation of the stable glasses into the supercooled liquid at temperatures slightly above Tg.
