Aqueous Fabrication of pH-Gated, Polymer-Brush-Modified Alumina Hybrid Membranes

Harm-Anton Klok, Caroline Sugnaux

In this Article, we studied the surface immobilization of five organic-acid-modified atom-transfer radical polymerization (ATRP) initiators based on salicylic acid, catechol, phthalic acid, and m- and p-benzoic add on alumina, and we also investigated the ...

Articular cartilage is a soft tissue that covers the ends of articulating bones, and is essential for maintaining joint motion, i.e. translation and rotation between the bones. Articular cartilage nevertheless has a limited capacity for self-repair, and ca ...

EPFL2012

Nanocomposite materials based on a HBP and silica are produced using either a dual-cure sol/gel and photopolymerization process or by mixing silica nanoparticles with the HBP. In both cases the conversion of the HBP is independent of composition and obeys ...

Arrested demixing opens route to bigels

Nicolas Dorsaz, Francesco Varrato, Giuseppe Foffi, Maxim Belushkin

Understanding and, ultimately, controlling the properties of amorphous materials is one of the key goals of material science. Among the different amorphous structures, a very important role is played by colloidal gels. It has been only recently understood ...

Low-Stress UV-Curable Hyperbranched Polymer Nanocomposites for High-Precision Devices

Valérie Geiser

The aim of this thesis was to investigate the process-structure-property relationships of UV-curable hyperbranched polymer (HBP)/silica nanocomposites. Special attention was paid to the interplay between photo-conversion, rheological behavior, shrinkage, a ...

A facile strategy for the modification of polyethylene substrates with non-fouling, bioactive poly(poly(ethylene glycol) methacrylate) brushes

Harm-Anton Klok, Jeffrey Alan Hubbell, Brian Pullin

This manuscript reports a facile strategy for the modification of polyethylene, a widely used biomaterial, with a thin non-biofouling coating that can act as a platform to introduce biochemical cues to control and direct, e.g., cell adhesion and proliferat ...

We investigate the structural, dynamical, and rheological properties of colloid-polymer mixtures in a volume fraction range of φ=0.15-0.35. Our systems are density-matched, residual charges are screened, and the polymer-colloid size ratio is ∼0.37. For the ...

Macrocyclization of enzyme-based supramolecular polymers

Maartje Martina Cornelia Bastings

AB type monomers for supramolecular polymers have been developed based on the strong and reversible noncovalent interaction between ribonuclease S-peptide (A) and S-protein (B), resulting in an active enzyme complex as the linking unit. Two AB-type protein ...

Biomimetic PEG hydrogels crosslinked with minimal plasmin-sensitive tri-amino acid peptides

Matthias Lütolf, Jeffrey Alan Hubbell, Simone Rizzi, Martin Ehrbar

Semi-synthetic, proteolytically degradable polymer hydrogels have proven effective as scaffolds to augment bone and skin regeneration in animals. However, high costs due to expensive peptide building blocks pose a significant hurdle towards broad clinical ...

Degradable Polymer Brushes Prepared via Surface-Initiated Controlled Radical Polymerization

Harm-Anton Klok, Nicolas Bertrand Schüwer, Carl Riachi

Hydrolytically degradable polymer brushes would represent an interesting platform for the development of functional coatings for various biomaterials applications In this manuscript, the surface- initiated atom transfer radical copolymerization of 5.6-benz ...
