Reference fluids, thermodynamic consistency

Besides shear-induced phase transitions, Uquid-gas equilibria in confined phases have been extensively studied in recent years, both experimentally [149-155] and theoretically [156-163]. For example, using a volumetric technique, Thommes et al. [149,150] have measured the excess coverage T of SF in controlled pore glasses (CPG) as a function of T along subcritical isochoric paths in bulk SF. The experimental apparatus, fully described in Ref. 149, consists of a reference cell filled with pure SF and a sorption cell containing the adsorbent in thermodynamic equilibrium with bulk SF gas at a given initial temperature T,- of the fluid in both cells. The pressure P in the reference cell and the pressure difference AP between sorption and reference cell are measured. The density of (pure) SF at T, is calculated from P via an equation of state. 

Chapter 1 provides a summary outlook on this complex topic with suggested three key references that address the static and dynamic mechanical behavior and associated degradation of composites from fluid exposure. Since the topic requires mastery of polymer science and engineering, engineering mechanics, chemical and polymer characterization, and thermodynamics of multi-phase materials, the author s perspective is more slanted on solid mechanics aspect of these materials. Jack had consistent financial support for three decades to study this topic from the Solid Mechanics Program managed by Dr. Yapa Rajapakse at the United States Office of Naval Research (ONR). Thus, the author is uniquely qualified to address this complex topic.
