Characterization of Hybrid Materials by Means of Inverse Gas Chromatography and Chemometrics

“…However, the analysis (evaluation) of the relationship between χ′ 23 value and the type of test solute used in IGC experiment is a hard task. This is a well known problem in the IGC literature 21,28,29. Values of Flory–Huggins interaction parameter for hybrid materials are collected in Table 2.…”

“…It is also possible to quantify the magnitude of the interaction between constituents of complex material, which was expressed using Flory–Huggins parameter χ′ 23 20,21 where χ ′ 1m denotes the Flory–Huggins interaction parameter for test solute–hybrid material pair, whereas χ ′ 12 and χ ′ 13 are Flory–Huggins parameters for test solute–component (two or three) pairs, respectively; ϕ 2 and ϕ 3 denote volume fraction of component in examined material.…”

Investigation of Polymers by Inverse Gas Chromatography

“…Now IGC is a reliable source of information on absorption and adsorption in polymers and on polymer properties. Numerous reviews and several books have been written on IGC. − Some of them were published 20–40 years ago. − Though being brilliant or simply useful, today they are rather outdated. In the 21st century researchers returned many times to the subjects of IGC. − A special book was published dealing with general questions of IGC.…”

“…Numerous reviews and several books have been written on IGC. − Some of them were published 20–40 years ago. − Though being brilliant or simply useful, today they are rather outdated. In the 21st century researchers returned many times to the subjects of IGC. − A special book was published dealing with general questions of IGC. It should be noted that most of those reviews focused on such subjects as polymer surface studies and polymer blends, ,,, determination of T g and other properties of polymers, , investigation of surfactants, pharmaceuticals, and fibers. , Meanwhile, some important issues did not receive proper attention in the existing literature, for example, thermodynamics of glassy polymers, IGC as a probe method for investigation of free volume in polymers, and some others.…”

“…10−19 A special book 10 was published dealing with general questions of IGC. It should be noted that most of those reviews focused on such subjects as polymer surface studies and polymer blends, 11,14,15,18 determination of T g and other properties of polymers, 13,19 investigation of surfactants, pharmaceuticals, 18 and fibers. 11,12 Meanwhile, some important issues did not receive proper attention in the existing literature, for example, thermodynamics of glassy polymers, IGC as a probe method for investigation of free volume in polymers, and some others.…”
