Mechanochemistry harnesses mechanical force to facilitate chemical reactions. Traditionally, the field of polymer mechanochemistry has used methods to activate chemical bonds, which use forces that are larger than those that are required to break a covalen ...
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 ...
The invention describes a composition containing a) a functionalized polymer (10) that comprises at least one polymer segment (13) and at least two polymer aggregating segments (11,12) capable of forming non-covalent bonds based on a supramolecular interac ...
Phase separation of immiscible fluids is a common phenomenon in polymer chemistry, and is recognized as an important mechanism by which cells compartmentalize their biochemical reactions. Biomolecular condensates are condensed fluid droplets in cells that ...
A method of producing a cryogel-based multicompartment 3D scaffold is herein disclosed. The method comprises the steps of: a) providing a first frozen polymeric layer on a refrigerated support kept at subzero temperature; b) providing subsequent polymeric ...
We demonstrate the fabrication of a 3D polymer/glass micromechanical sensor by combining two femtosecond laser direct writing processes: subtractive laser-assisted chemical etching combined with additive two-photon polymerization techniques. In the first s ...
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 ...
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 ...
Chain-end-labeled polymers are interesting for a range of applications. In polymer nanomedicine, chain-end-labeled polymers are useful to study and help understand cellular internalization and intracellular trafficking processes. The recent advent of fluor ...
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 ...
