Abstract

Summary: A unified model is developed for the finite sizeโ€effect on the glassโ€transition temperature of polymers, T~g~(D), where D denotes the diameter of particles or thickness of films. In terms of this model, T~g~ depends on both the size and interface conditions. The predicted results are consistent with the experimental evidence for polystyrene (PS) particles and films with different interface situations.

T~g~(D) function of freeโ€standing PS films.

Lap shear and friction force measurements were carried out on a series of monodisperse polystyrene (PS) films below the corresponding glass-transition temperatures. It showed that adhesion between the PS/PS interface was possible at the temperature below the bulk T g , and the lower the molecular we

The glass transition can be measured at different experimental conditions. Using spectroscopic methods at relative high frequency the a-relaxation is measured in the thermodynamic equilibrium. In the caloric case we call this phenomenon thermal relaxation transition (TRT). With a conventional differ
