Revealing the Formation Dynamics of Janus Polymer Particles: Insights from Experiments and Molecular Dynamics

Philip Robin Loche

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 ...

Washington2023

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 ...

An Acid Test: Facile SI-ARGET-ATRP of Methacrylic Acid

Harm-Anton Klok, Piotr Mocny

Atom transfer radical polymerization (ATRP) of methacrylic acid (MAA) is challenging. Herein is reported a study of conditions for facile surface-initiated ATRP by activator regenerated electron transfer (SI-ARGET-ATRP) growth of poly-methacrylic acid (PMA ...

Silicones with enhanced permittivity for dielectric elastomer actuators

Frank Nüesch

The research efforts for silicone based elastomers with high dielectric permittivity (epsilon') intensified significantly in the last years since such materials would allow the construction of dielectric elastomer actuators (DEA) with low operation voltage ...

Controlled radical polymerization techniques such as RAFT allow fine control over polymer molecular weight and architecture. These techniques, however, do not eliminate compositional drifts in copolymerizations, which are the consequence of differences in ...

Royal Society of Chemistry2015

The surface chemistry at the DNA recognition and binding interface plays an important role in determining the performance of DNA microarrays and DNA biosensors. Surface-initiated controlled radical polymerization (SI-CRP) reactions represent a powerful too ...

UV-cured transparent magnetic polymer nanocomposites

Yves Leterrier, Marco Sangermano, Tommaso Nardi

Magnetite nanoparticles are synthesized by thermal decomposition of Fe(acac)(3) and subsequently coated with a silica shell exploiting a water-in-oil synthetic procedure. The as-produced nanopowder is mixed with a photocurable hyperbranched resin and the p ...
