Anisotropic wetting of microstructured surfaces as a function of surface chemistry.
In order to study the influence of surface chemistry on the wetting of structured surfaces, microstructures consisting of grooves or squares were produced via hot embossing of… Expand
Functional Polymer Structures
Polymer micro- and nanografting is introduced in the context of different methods to locally endow polymers with selected functionalities. The second part of the chapter gives an introduction to… Expand

A method to create a wettability gradient by variation of the chemical functionality in a polymer brush is presented. A poly(N-methyl-vinylpyridinium) (QP4VP) brush was created on a… Expand
Functionalization of fluoropolymer surfaces with nanopatterned polyelectrolyte brushes
Abstract We present a strategy to combine the excellent bulk properties of fluoropolymer substrates with the wide range of functionalities of surface-grafted polyelectrolyte brushes. Patterns of… Expand
Functionalization of Fluropolymers and Polyolefins via Grafting of Polyelectrolyte Brushes From Atmospheric‐Pressure Plasma Activated Surfaces
ETFE, PE, and PP surfaces were functionalized by a procedure involving the activation of the substrates with cold, atmospheric-pressure helium plasma, formation of surface-bound peroxides in air, and… Expand
Polymer-on-Polymer Structures Based on Radiation Grafting
Radiation grafting—a process comprising radiation-induced formation of radicals in polymer substrates followed by a graft polymerization of a selected monomer—is an attractive way to endow polymers… Expand
Characterization Challenges of Micro- and Nanografted Polymer Systems
This chapter discusses challenges for the application of analytical tools for the characterization of grafted polymer structures on polymeric substrates. The chapter presents strategies to overcome… Expand
