Haloform adsorption on crystalline copolymer films of vinylidene fluoride with trifluoroethylene

Isomeric effects with di-iodobenzene (C6H4I2) on adsorption on graphite

“…The clean graphite surface was characterized by core level X-ray photoemission (XPS), and combined valence band photoemission and inverse photoemission, as described elsewhere [29]. An Al K α (ћω = 1486.6 eV) was used for the XPS studies with the electrons collected along the surface normal and analyzed in a hemispherical SCIENTA SES-100 electron energy analyzer.…”

“…There is thus a need to invoke intermolecular interactions that can include intermolecular screening [11,42], chemical shifts due to intermolecular hybridization [43], as well as final state effects attributable to screening from the substrate [33,34].…”

Adsorbate/absorbate interactions with organic ferroelectric polymers

“…Reversible bromoform adsorption on crystalline P(VDF-TrFE 70:30) is both associative and reversible [31]. Molecular bromoform adsorption appears to be an activated process at 120 K with enhanced adsorption following the initial adsorption of bromoform.…”

“…Molecular bromoform adsorption appears to be an activated process at 120 K with enhanced adsorption following the initial adsorption of bromoform. Strong intermolecular interactions are also implicated in the presence of a weak shake off or screened photoemission final state, whose intensity scales with the unscreened photoemission final state [31], as seen in Figure 7.…”

“…are approximately at a binding energy of 72.1 ± 0.1 eV with low bromoform exposure and increase to 72.6 ± 0.1 eV with higher exposures at 120 K [31]. These bromine 3d core level binding energy features are a signature of molecular bromoform [31,32].…”
