Phase transitions polymers role (10 resultados)

Hardcover. Condición: New. Estado de la sobrecubierta: New. 1st Edition. Phase transition play a central role in connecting the field of structural analysis and dynamics in changes. This book attempts to utilize the concepts of metastable states and metastability to link these two research fields and illuminate the physics beind polymeric phase transitions. A classical metastable state possesses a local free energy minimum at infinite size but not a global one, This concept is phase size independent. We now know that two types of metastable states can be identified. The first type is associated with the supercooling or superheating of a phase before a phase transition has time to occur, while the second type is associated with competing kinetic pathways caused by the existence of multiple free energy paths to reach the equilibrium phase. We have studied a number of experimental results and proposed that there are a wide range of metastable states in polymers at different length and time scales. The effect of phase size on metastability is specifically introduced and discussed. Metastable states can be identified by structural and morphological investigations of crystallization along with mesophase transitions, liquid-liquid phase separation, vitrification and gel formation, as well as combinations of these transformation processes. The phase behavior of polymers is thus dominated by the interdependence of metastable states at different length and time scales.…

Hardback. Condición: New. A classical metastable state possesses a local free energy minimum at infinite sizes, but not a global one. This concept is phase size independent. We have studied a number of experimental results and proposed a new concept that there exists a wide range of metastable states in polymers on different length scales where their metastability is critically determined by the phase size and dimensionality. Metastable states are also observed in phase transformations that are kinetically impeded on the pathway to thermodynamic equilibrium. This was illustrated in structural and morphological investigations of crystallization and mesophase transitions, liquid-liquid phase separation, vitrification and gel formation, as well as combinations of these transformation processes. The phase behaviours in polymers are thus dominated by interlinks of metastable states on different length scales. This concept successfully explains many experimental observations and provides a new way to connect different aspects of polymer physics.…
