Architecturally Diverse Polymer Brushes Prepared via Surface-Initiated Atom Transfer Radical Polymerization
Polymer brushes, which are polymers anchored to a solid substrate by one chainend, have the ability to modify the properties of an underlying substrate, offeringintriguing features such as enhanced lubrication, reduced friction, colloidal stability, and an ...
EPFL2023Revealing the Formation Dynamics of Janus Polymer Particles: Insights from Experiments and Molecular Dynamics
Seeded emulsion polymerization is one of the best-known methods for preparing polymer particles with a controlled size, composition, and shape. It first requires the preparation of seed particles, which are then swollen with additional monomer (the same as ...
Washington2023Influence of the molecular weight and physical properties of a thermoplastic polymer on its dynamic wetting behavior
The wetting dynamics of molten thermoplastic polymers, which are known to influence the force balance of the triple line, are not understood properly despite their importance in many industrial processes. In particular, the influence of the molecular weigh ...
PERGAMON-ELSEVIER SCIENCE LTD2023Functional and Responsive Polymers via Controlled Radical Polymerization
This Thesis is built around 4 topics, which share in common that they all take advantage of the assets of controlled radical polymerization to either (i) prepare well-defined model systems to address fundamental research questions with regard to the sensit ...
EPFL2020Complex polymer topologies and polymer-nanoparticle hybrid films prepared via surface-initiated controlled radical polymerization
Advances in controlled radical polymerization over the past two decades have transformed the ability to produce molecularly well-defined, chain-end tethered polymer brush films. The assets of controlled radical polymerization reactions have impacted the sy ...
PERGAMON-ELSEVIER SCIENCE LTD2020Composition and method for the preparation of sheets, films, fibers, and molded parts
Holger Frauenrath, Daniel Görl, Oguzhan Oguz
The invention describes a composition containing a) a functionalized polymer (10) that comprises at least one polyester segment (13) and at least one, in particular at least two, polymer aggregating segment (11, 12) capable of forming non-covalent bonds ba ...
2020Selection of Water-Soluble Chitosan by Microwave-Assisted Degradation and pH-Controlled Precipitation
Sandrine Gerber, Yann Lavanchy, Céline Marie Anne Journot, Laura Camille Louise Nicolle
In the field of gene therapy, chitosan (CS) gained interest for its promise as a non-viral DNA vector. However, commercial sources of CS lack precise characterization and do not generally reach sufficient solubility in aqueous media for in vitro and in viv ...
2020Synthesis of Loop Poly(Methyl Methacrylate) Brushes via Chain-End Postpolymerization Modification
Polymer brushes are typically densely grafted assemblies of polymer chains that are tethered via one end group to a solid substrate. Anchoring linear polymer chains via both end groups to a surface results in loop-type polymer brushes. Although loop polyme ...
AMER CHEMICAL SOC2019Swelling-Induced Chain Stretching Enhances Hydrolytic Degrafting of Hydrophobic Polymer Brushes in Organic Media
Hydrophilic polymer brushes grown via surface‐initiated polymerization from silicon oxide surfaces can detach or degraft in aqueous media. Degrafting of these chain end‐tethered polymers is believed to involve hydrolysis of bonds at the polymer–substrate i ...
2019Polymer brush interfaces for protein biosensing prepared by surface-initiated controlled radical polymerization
Harm-Anton Klok, Mark Billing, Michael Badoux
Thin polymer films that are able to bind proteins are of great relevance for a wide variety of biosensor and biochip applications. Some of these applications require films that have high protein binding capacities while others call for surfaces that allow ...
