Effect of the molecular structure on the adsorption of conditioning polyelectrolytes on solid substrates

Interfacial characterization of Pluronic PE9400 at biocompatible (air–water and limonene–water) interfaces

“…On the contrary, at the limonene-water interface the experimental data deviate from the behavior of a pure diffusion adsorption. Previous works show the occurrence of a slower reorganization process which follows the first diffusion step in the adsorption kinetic of Pluronics at fluid and solid interfaces [21,52]. In order to take into account this slower process a theoretical model developed elsewhere [50] was used.…”

Kinetic aspects of the adsorption of xyloglucan onto cellulose nanocrystals

“…The D surf values decreased with increasing concentration from 3.3 10 -7 cm 2 s -1 for XG at 10 µg mL -1 to 4.3 10 -6 cm 2 s -1 at 0.3 µg mL -1 . [52][53][54] At very dilute regimes, below 3.5 µg mL -1 , XG will rearrange until forming a tightly anchored layer (trains) with all sugar residues interacting with the CNC surface. It is assumed that the β-(1-4)-linked backbones of XG and cellulose interact by hydrogen bonds and van der Waals interactions, and the system is stabilized by interactions with the XG side chains.…”

Influence of the molecular architecture on the adsorption onto solid surfaces: comb-like polymers

“…[34][35][36] The kinetic data presented below can be described as those from a bimodal process in the way proposed by Chiang et al 37 Our data agree with the results previously reported for other polyelectrolyte systems. 15 The adsorption process proceeds in two steps. The first fast step can be related to the transport of the chains to the surface.…”

“…13 These particular properties make comb-like polymers attractive for applications such as the fabrication of biomedical devices, 14 or as conditioning agents in cosmetic applications. 15 One of the most important advantages of the use of this type of comb-like polymers, in relation to other methods of fabrication of surfaces with grafted chains, is the possibility of tailoring the grafting density prior to the adsorption process. The latter allows selecting a polymer with the desired grafting ratio (ratio between the number of monomer units on the backbone and the number of grafted chains).…”
