Conductive silicone elastomers electrodes processable by screen printing

Frank Nüesch, Jose Enrico Quijano Quinsaat

Conductive inks consisting of graphene and carbon black conductive fillers into a polydimethylsiloxane (PDMS) matrix, which can be processed into thin films by screen printing are developed. The influence of filler composition and content on mechanical and ...

Hydrophobization of silver nanoparticles through surface-initiated atom transfer radical polymerization

Heinrich Hofmann, Frank Nüesch, Jose Enrico Quijano Quinsaat

This work describes the synthesis of poly(methyl methacrylate) (PMMA)-coated Ag@SiO2 core-shell particles by conducting a Surface-Initiated Atom Transfer Radical Polymerization (SI-ATRP). Silver nanoparticles (AgNPs) were first prepared by the polyol synth ...

Highly stretchable dielectric elastomer composites containing high volume fractions of silver nanoparticles

Heinrich Hofmann, Jose Enrico Quijano Quinsaat

The dielectric permittivity (epsilon') of a polymeric material can be significantly increased when blended with conductive fillers at concentrations approaching the percolation threshold. However, reproducible synthesis of such composites is after decades ...

Continuous Polyol Synthesis of Metal and Metal Oxide Nanoparticles Using a Segmented Flow Tubular Reactor (SFTR)

Paul Bowen, Andrea Testino, Christoph Stähli, Jose Enrico Quijano Quinsaat, Frank Pilger

Over the last years a new type of tubular plug flow reactor, the segmented flow tubular reactor (SFTR), has proven its versatility and robustness through the water-based synthesis of precipitates as varied as CaCO3, BaTiO3, Mn((1-x))Ni(x)C(2)O(4)2H(2)O, YB ...

Continuous Production of Tailored Silver Nanoparticles by Polyol Synthesis and Reaction Yield Measured by X-ray Absorption Spectroscopy: Toward a Growth Mechanism

Paul Bowen, Heinrich Hofmann, Frank Nüesch, Andrea Testino, Christian Ludwig, Jose Enrico Quijano Quinsaat

Two complementary topics are discussed: (i) the continuous production of silver nanoparticles (AgNPs) and (ii) the measurement of reaction yield by X-ray absorption near-edge spectroscopy (XANES). The continuous polyol synthesis of AgNPs in grams amount an ...

Dielectric properties of silver nanoparticles coated with silica shells of different thicknesses

Heinrich Hofmann, Jose Enrico Quijano Quinsaat

Core/shell nanoparticles having metallic silver nanoparticle cores of similar to 38 nm in diameter and silica shells of different thicknesses ranging from similar to 3.6-20 nm were prepared. For the silica coating, a slightly modified Stober method was use ...
