“…The reason for this is the uncertainty of the molecular surface area values of the adsorbed species [25,105,118]. Molecular areas of adsorbed molecules may be distorted by forces that are exerted by the surface.…”

“…Furthermore, different methods are in use for the estimation of the molecular areas, which may result, in some cases, in different values [111]. Also, the temperature influence on the molecular areas is not usually taken into account [25,118]. Consequently, IGC evaluations of g d s , using this approach, must be viewed with some caution.…”

“…More detailed descriptions of solid surfaces would necessitate the determination of adsorption isotherms of site energy distributions [73,116,[138][139][140][141][142]. In many instances, however, the dominant surface interactions of a solid will be those involving the high-energy sites [11,25].…”

“…These specific interactions are of a highly directional nature and are present in addition to the dispersive forces. A current view, pioneered by Fowkes [14,[19][20][21][22][23][24][25], which is increasingly accepted, suggests that the totality of specific interactions may be viewed as Lewis acid-base forces. This approach has been supported by experimental results [24].…”

The properties of a polymeric system are a consequence of the interactions that occur between the various components of these complex systems. These components may vary significantly in terms of chemical nature (e.g. organic/inorganic), physical properties (e.g. particle size, surface area, molecular weight), structural characteristics and proportion in the formulations composition. This review paper addresses the major approaches in use regarding the analysis of the interactions that occur between the polymeric system components and the use of such approaches in the interpretation of the chemical, physical and thermodynamic properties of these systems. Special attention is given to the technique of inverse gas chromatography.A case study is presented, where use was made of inverse gas chromatography to characterize thermodynamically the surface of the major components of pigmented PC/PBT blends. The concept of Lewis acidity/basicity was used in the interpretation of the intermolecular interactions nature and potential in these blends, as encountered in phase separation and phase preferences phenomena and as expressed in the morphology, the physical and the mechanical properties of these commercially important composites. #

A time-dependent oxidation of carbon fibers in boiling nitric acid was used to investigate the influence of a modification of the fiber surface properties on the adhesion strength with an acrylate resin cured by electron beam (EB). For each time of treatment, a characterization of the surface topography and the surface chemistry was done (topography at a micrometric and nanometric scale, specific surface area, temperature programmed desorption, X-ray photoelectron spectroscopy analysis). The oxidation of the fiber surface in boiling nitric acid created a rough surface, which significantly increased the specific surface area, and also generated a high density of hydroxyl groups, carboxylic acids and lactones in comparison to untreated fibers. The adhesion strength with the acrylate resin cured by EB was measured by a pull-out test. For comparison, an isothermal ultraviolet curing of the matrix was also investigated. The value of the interfacial shear strength, determined by the Greszczuk's model, was increased by the oxidation of the carbon fiber surface for both curing processes, but lower values were systemically obtained with EB curing. Figure 11. Roughness of the surface of IMS 5000 fibers, perpendicular to the fiber axis, after different times of oxidation: a = 10 min, b = 20 min, c = 45 min, d = 1 h, e = 90 min, f = 2 h.
