First step in the design and realisation of a 'smart' switchable surface
… in the design and fabrication of a double armed switchable surface that exhibits dynamic changes in its interfacial properties in terms of bio-recognition, in response to an electrical potential (Figure 1a). The aim of the work herein is to develop a suitable synthetic strategy to ensure the …

Design and Characterization of Central Functionalized Asymmetric tri-Block Copolymer Modified Surfaces
… were designed as a new type of polymer brush surface modifier, with a short central functionalized block that can form chemical bonds with a suitable substrate surface. A combination of sequential living anionic polymerization and polymer modification reactions were used for the synthesis of …

Poly(vinyl alcohol) based hydrogen-bonded multilayers : from pH-controlled multi-stage dissolution to zwitter-wettable surfaces
… for developing a diverse range of functional surfaces including antifogging coatings, switchable surfaces and stimuli-responsive hydrogels. The first part of this thesis is focused on extending hydrogen-bonding driven polymer thin film assembly by developing a novel systematic framework in …

Self-Organized Nanostructures from Stimuli-Responsive Triblock Terpolymers
… potential for various applications, such as switchable surface coatings and non-viral gene delivery. The triblock terpolymers employed in all studies are polybutadiene-block-poly(tert-butyl methacrylate)-block-poly(2-(dimethylamino)ethyl methacrylate) (PB-b-PtBMA-b-PDMAEMA, BTD), which …

Photochemische Fixierung von Strukturen in Grenzflächen mit polymeren Bürsten
Binäre Polymerbürsten bestehen aus zwei verschiedenen Polymertypen, die nebeneinander auf dem gleichen Trägermaterial verankert sind. Wenn diese Polymere unterschiedliche Benetzungseigenschaften haben, können damit schaltbare Oberflächen produziert werden. Abhängig vom Lösungsmittel, dem man die …

Switching of surface composition and morphology of binary polymer brushes
Switching of surface composition and morphology of binary polymer brushes in response to changes in solvent selectivity, heating above glass transition temperatures, and contact with a rubbery stamp was studied. The binary brushes: polystyrene/poly(2-vinyl pyridine) (PS/P2VP), …
