Fabrication of nanopore arrays and ultrathin silicon nitride membranes by block-copolymer-assisted lithography

Jeffrey Alan Hubbell, Harry Heinzelmann, Raphaël Pugin, Ana Maria Popa

Here we show a method for patterning a thin metal film using self-assembled block-copolymer micelles monolayers as a template. The obtained metallic mask is transferred by reactive ion etching in silicon oxide, silicon and silicon nitride substrates, thus ...

Surface Nanopatterning by Polymer Self-Assembly: from Applied Research to Industrial Applications

Jeffrey Alan Hubbell, Nicolas Blondiaux, Raphaël Pugin, Martha Liley, Ana Maria Popa

Complementary methods have been developed for surface nanostructuring using molecular self-assembly, reactive ion etching and replication techniques. First, controlled surface nanostructures with tunable lateral dimensions from tens of nanometer to tens of ...

Gold nanoring arrays from responsive block copolymer templates

Patrik Willi Hoffmann, Li Wang, Raphaël Pugin, Franck Montagne

We report a pH-mediated synthetic route for the production of ordered and size-tuneable arrays of gold nanorings using responsive block copolymer micelles as templates. ...

The systematic tunability of nanoparticle dimensions through the controlled loading of surface-deposited diblock copolymer micelles

Jürgen Brugger, Harry Heinzelmann, Sivashankar Krishnamoorthy, Raphaël Pugin

The continuous tunability of iron oxide nanoparticle dimensions is demonstrated using the pH controlled loading of ferric nitrate from aqueous solution into polystyrene–block–polyacrylic acid reverse micelles deposited on a silicon substrate. Quasi-hexagon ...

Tuning the Dimensions and Periodicities of Nanostructures Starting from the Same Polystyrene-block-poly(2-vinylpyridine) Diblock Copolymer

Jürgen Brugger, Harry Heinzelmann, Sivashankar Krishnamoorthy, Raphaël Pugin

The controlled tuning of the characteristic dimensions of two-dimensional arrays of block-copolymer reverse micelles deposited on silicon surfaces is demonstrated. The polymer used is polystyrene-block-poly(2-vinylpyridine) (91500-b-105000 g mol–1). Revers ...

Block copolymer micelles as switchable templates for nanofabrication

Jürgen Brugger, Harry Heinzelmann, Sivashankar Krishnamoorthy, Raphaël Pugin

Block copolymer inverse micelles from polystyrene-block-poly-2-vinylpyridine (PS-b-P2VP) deposited as monolayer films onto surfaces show responsive behavior and are reversibly switchable between two states of different topography and surface chemistry. The ...
