Emerging applications of stimuli-responsive polymer materials.
Responsive polymer materials can adapt to surrounding environments, regulate transport of ions and molecules, change wettability and adhesion of different species on external stimuli, or convertExpand

Protein adsorption on and swelling of polyelectrolyte brushes: A simultaneous ellipsometry-quartz crystal microbalance study
With a coupled spectroscopic ellipsometry-quartz crystal microbalance with dissipation (QCM-D) experimental setup, quantitative information can be obtained about the amount of buffer componentsExpand

Two-level structured self-adaptive surfaces with reversibly tunable properties.
We report a route to fabricate two-level structured self-adaptive surfaces (SAS) of polymer materials. The first level of structure is built by a rough polymer film that consists of needlelikeExpand

Protein resistance of PNIPAAm brushes: application to switchable protein adsorption.
Protein adsorption, as the primary process occurring when a foreign surface comes into contact with a biosystem, was studied on thin polymer brush films consisting of poly(N-isopropylacrylamide)Expand

Synthesis of Adaptive Polymer Brushes via “Grafting To” Approach from Melt
We report a simple method to synthesize binary polymer brushes from two incompatible polymers of different polarity. The synthetic route is based on a subsequent step-by-step grafting ofExpand

Biocompatible polymeric materials with switchable adhesion properties
We report on the design, investigation and comparison of the adhesive properties of poly-(N-isopropylacrylamide) and biocompatible polyethylene glycol-based thermoresponsive brushes. Specifically, aExpand

In situ studies on the switching behavior of ultrathin poly(acrylic acid) polyelectrolyte brushes in different aqueous environments.
The pH-dependent switching of a poly(acrylic acid) (PAA) polyelectrolyte brush was investigated in situ using infrared spectroscopic ellipsometry (IRSE). The brush was synthesized by a "grafting to"Expand

Lateral versus perpendicular segregation in mixed polymer brushes.
Grafting of incompatible polymers on a substrate prevents macrophase separation and the chains self-assemble laterally. Mixed brushes are exposed to different solvents and the morphology is observedExpand

One-Dimensional Aggregation of Regioregular Polyalkylthiophenes
Solvent-induced aggregation of regioregular head-to-tail poly(3-alkylthiophene)s (PATs) have been studied by means of AFM and UV−vis spectroscopy. In hexane, which is a good solvent for alkyl sideExpand

Temperature-sensitive swelling of poly(N-isopropylacrylamide) brushes with low molecular weight and grafting density.
Temperature-sensitive poly(N-isopropylacrylamide) (PNIPAAm) brushes with different molecular weights M(n) and grafting densities σ were prepared by the "grafting-to" method. Changes in theirExpand
