Reversibly Programmable Photonics via Responsive Polyelectrolyte Multilayer Cladding

Temperature responsive behavior of polymer brush/polyelectrolyte multilayer composites.

The complex interaction of polyelectrolyte multilayers (PEMs) physisorbed onto end-grafted polymer brushes with focus on the temperature-responsive behavior of the system is addressed in this work. The investigated brush/multilayer composite consists of a poly(styrene sulfonate)/poly(diallyldimethylammonium chloride) (PSS/PDADMAC) multilayer deposited onto the poly(N-isopropylacrylamide-b-dimet...

Responsive Polymer Photonics**

This thesis discusses innovative approaches to polymer-based photonic coatings, with the present chapter presenting an overview of developments in this field. The coatings in question can change their topological properties in a reversible, dynamic way when exposed to an external stimulus. This thesis will first describe photoresponsive coatings that change their surface topography and therefor...

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...

Elasticity of polyelectrolyte multilayer microcapsules.

We present a novel approach to probe elastic properties of polyelectrolyte multilayer microcapsules. The method is based on measurements of the capsule load-deformation curves with the atomic force microscope. The experiment suggests that at low applied load deformations of the capsule shell are elastic. Using elastic theory of membranes we relate force, deformation, elastic moduli, and charact...
