Synthesis and photopolymerization of Tween 20 Methacrylate/N-vinyl-2-Pyrrolidone blend

Jan-Anders Edvin Maansson, Dominique Pioletti, Pierre-Etienne Bourban, John Christopher Plummer, Ana Borges de Couraça

Poly(oxyethylene 20 sorbitan) monolaurate (Tween® 20) methacrylates were synthesized by coupling methacryloyl chloride (MeOCl) to Tween 20 in the presence of 4-(N,N-dimethylamino) pyridine, using THF as a solvent, in order to investigate their suitability ...

Controlled hydrogel photopolymerization inside live systems by X-ray irradiation

Giorgio Margaritondo

We successfully demonstrate the in situ formation by X-ray irradiation induced polymerization of a three-dimensional (3D) hydrogel based on poly(ethylene glycol) (PEG) diacrylate (PEG DA), with the option of heparin incorporation to enhance cell adhesion. ...

Drop-On-Demand Inkjet Printing of SU-8 Polymer

Jürgen Brugger, Alcherio Martinoli, Vahid Fakhfouri, Grégory Mermoud, Joo Yeon Kim

This paper presents drop-on-demand inkjet printing of SU-8 on functionalized surfaces for direct printing of computer controlled polymer patterns. The high viscosity of SU-8 required an in-depth investigation of the print parameters such as pulse amplitude ...

Local infiltration of planar photonic crystals with UV-curable polymers

Romuald Houdré, Rolando Ferrini, Libero Zuppiroli, Laurent Balet, Pascale El-Kallassi

We present the local polymer infiltration of planar photonic crystal cavities via a maskless laser-writing technique. After the infiltration of the air holes with a UV-curable monomer a focused laser is used to locally polymerize the monomer in selected ho ...

Dark curing kinetics of UV printing inks by real-time ATR-FTIR spectroscopy

Eric Jacques Nouzille

In UV-curable printing technology, an ink or a varnish is exposed to the UV-light source within a fraction of a second. Subsequent polymerization therefore proceeds in the dark, referred to as dark curing. Because dark curing can be critical and contribute ...

Synthesis of uniform, non-natural oligomers

Harm-Anton Klok, Nadja Franz

Oligomers with well-defined chain lengths are of interest as foldamers, are important as model compounds for high-molecular-weight polymers and find application in electrooptic and sensory devices. This account presents an overview of the strategies that a ...
