2015, Journal of Pharmaceutical SciencesCitation Excerpt :The parameters of the Langmuir adsorption isotherm model (Table 1) including the Langmuir constant (K) and the maximum amount adsorbed (Amax) describe the affinity of the adsorbate for a specific adsorbent and the adsorption capacity of the adsorbent, respectively. The polymer adsorption process depends on several factors including the nature of the polymer, solvent, and the surface of the adsorbent.35–37 The adsorption behavior of a polymer could be influenced by the adsorption energy and related intermolecular polymer–solvent, solvent–surface, and polymer–surface interactions such as van der Waals, electrostatic, hydrogen bonding, and hydrophobic interactions.1,38,39
Adsorption of poly(hydroxystearic acid) to TiO<inf>2</inf> nanoparticles, studied using gel permeation chromatography
2015, Colloids and Surfaces A: Physicochemical and Engineering AspectsCitation Excerpt :As seen in the insets in Figs. 2 and 3, the Langmuir isotherm fits quite well with the experimental data for all dispersants in both solvents (R2 > 0.99). The adsorbed amount is a function of molecular weight (and in the case of the oligermerics, molecular weight distribution), solubility in the solvent (and therefore relative solubility parameters) characterised by the Flory Huggins interaction parameter χ, affinity for the surface of the adsorbing functional group(s), and repulsion from the solvent of this functional group [17,18]. The adsorption mechanism of all three dispersants is likely to be similar: they are all fatty acids with a single terminal acid group which can interact with hydroxyl groups at the metal oxide surface; fatty chains extend into the solvent to provide stability.
Scattering approaches to probing surface layers under confinement
2015, Current Opinion in Colloid and Interface ScienceCitation Excerpt :The wide range of applications for adsorbed polymers has made these systems highly desirable subjects for confinement investigations, and a wealth of SFA and AFM force measurements underpin understanding in this field. Partnered with the experimental characterization of adsorbed polymers, the theoretical framework of Scheutjens–Fleer theory [18] provides a model to describe the polymer volume fraction profile in a solvent; this lattice model makes experimentally verified predictions for the volume fraction profiles [19–21] with NMR, small-angle neutron scattering (SANS), and neutron reflection playing important roles. In probing the adsorbed polymers with neutron reflection, a significant technical limitation must be considered: a large neutron beam footprint (500 to [2500] mm2) is required in order to finish one experiment in a reasonable time frame [7].
Layer-by-layer assembly of iron oxide magnetic nanoparticles decorated silica colloid for water remediation
2014, Chemical Engineering JournalCitation Excerpt :The presence of PDDA polyelectrolyte on the outmost layer of silica colloids caused a reversal of zeta potential to +58.3 mV. On top of that, the orientation of the adsorbed polyelectrolyte on silica particle surface is most probably appeared as trains, loops and tails which has been well-investigated by the Fleer’s group [53,54]. This adsorbed layer of cationic PDDA serves as the binding agent to facilitate the attachment of negatively charged IOMNPs with zeta potential at −6.6 mV.
