Spray Assembled, Cross-Linked Polyelectrolyte Multilayer Membranes for Salt Removal

Spray-evaporation assembled graphene oxide membranes for selective hydrogen transport

Divalent-anion salt effects in polyelectrolyte multilayer depositions.

We systematically investigate the effects of divalent anions on the assembly of polyelectrolyte multilayers by fabricating polystyrene sulfonate (PSS)/polyallylamine hydrochloride (PAH) multilayer films from aqueous solutions containing SO(4)(2-), HPO(4)(2-), or organic dicarboxylate dianions. The chosen concentrations of these anions (i.e., ≤0.05 M) allow us to isolate their effects on the ass...

Ultrathin cross-linked nanoparticle membranes.

The fabrication of functional nanostructured materials for sensing, encapsulation and delivery requires practical approaches to self-assembly on multiple length scales and the synthesis of tough yet permeable structures. Here, the self-assembly of functionalized, photoluminescent nanoparticles at liquid interfaces, followed by cross-linking of the associated ligands, affords robust membranes th...

Polyelectrolyte Multilayer Capsule: a Review

Polyelectrolyte Adsorption and Multilayer Formation

In this chapter, we review our recent theoretical work on the formation of polyelectrolyte multilayers. The first layer is obtained by polyelectrolyte adsorption on a surface with an opposite charge. The adsorbed polyelectrolyte charge is sufficient to invert the charge of the surface. Each subsequent layer is bound to the previous one by the formation of a polyelectrolyte complex. Using a Deby...
