Bioadhesion to model thermally responsive surfaces
… focuses on the characterization of two surfaces: mixed self-assembled monolayers (SAMs) of hexa(ethylene glycol) and alkyl thiolates (mixed SAM) and poly(N-isopropylacrylamide) (PNIPAAm). The synthesis of hexa(ethylene gylcol) alkyl thiol (C11EG6OH) is presented along with the mass …

Functional and responsive surfaces via initiated chemical vapor deposition (iCVD)
Stimuli-responsive polymers provide a method to control system behavior through the use of an external stimulus, such as temperature, pH, or electric fields among others. Temperature-responsive polymers, especially those based on N-isopropylacryalmide (NIPAAm), are of particular research interest …

Dielectric Elastomer Actuators in Electro-Responsive Surfaces Based on Tunable Wrinkling and the Robotic Arm for Powerful and Continuous Movement
… for years. Recently the DEA-based deformable surfaces have demonstrated controllable microscale roughness, ease of operation, fast response, and possibilities for programmable control. DEA muscles used in bioinspired robotic arms for large deformation and strong force also become desirable for …

Reversible stimulus-responsive polymers for the control of the surface interfacial and nanomechanical properties
Surfaces with reversible stimulus-responsive properties have great potential for a wide variety of applications, such as transport, separation, and detection of biomolecules, controlled adhesion, friction, and lubrication in microfluidic systems, and force or displacement generation in micro- and …

Direct Measurements of Polyelectrolyte Brush Responses using Atomic Force and Optical Microscopy
… of the response properties of these polymer surfaces. For that purpose new methods are developed which combine force spectroscopy and optical microscopy. As well, established physico-chemical techniques are used. Polymer brushes provide an excellent building block for responsive surfaces. …

Smart magnetic affinity adsorbents
As the focus of research on ‘adaptive/responsive’ surfaces has in recent years contributed strongly towards the design of surface materials with ‘intelligent’ or ‘smart’ behaviour, current superparamagnetic adsorbents being employed both in small and large scale operations can be surface modified …

Synthesis, physico-chemical properties and potential applications of colloidal gel particles
… microgels were deposited on different solid surfaces to produce new environmental responsive surfaces. The mass of microgel particles deposited on glass pre-treated with acid, glass pre-treated with base, quartz, stainless steel, gold and Teflon at 25°C and 60°C was determined using …

Droplet levitation and underwater plastron restoration using aerophilic surface textures
… the use of active components in liquids and responsive surfaces to resist the wetting of water on solid surface textures. When a superhydrophobic surface comes into contact with water, it traps a thin layer of air (plastron) within its surface texture. This entrapped air is advantageous for …

Synthesis and Characterization of Novel Polymers for Functional and Stimuli Responsive Silicon Surfaces
… techniques to achieve functional and stimuli responsive coatings on silica surfaces are described. Since microscopic features on a surface influence the overall wetting properties of the surface, a systematic investigation of the influence of polymer architecture on the microscopic …
