Abstract Details

2005, Doctor of Philosophy, Case Western Reserve University, Macromolecular Science.
Although permeability of small molecules is often measured as an important performance property, deeper analysis of the transport characteristics provides insight into polymer structure, especially if used in combination with other characterization techniques. Transport of small gas molecules “senses” the permeable amorphous structure and probes the nature of free volume. This work focuses on oxygen transport, supplemented with other methods of physical analysis, as a probe for: 1) the nature of free volume in the oriented glassy state, 2) the role of amorphous phase orientation and strain-induced crystallization on oxygen barrier properties of polyester blends, and 3) the nature of interphase between immiscible amorphous polymers in forced-assemblies.
