Easy release fluoropolymer molds for micro- and nano-pattern replication

Hans Jörg Mathieu, David Barbero

A mold (35) for use in nano- or micro-replication processes on thermoplastic polymer substrates (20), comprises a nano- or micro-structured fluoropolymer surface that, when the mold (35) is used in a nano- or micro-replication process, serves for the appli ...

Paraffin-PDMS composite thermo microactuator with large vertical displacement capability

Nico de Rooij, Danick Briand, Herbert Shea

We have micromachined and tested the first paraffinPDMS composite thermal microactuator having multi shot large vertical displacement capabilities ( 160 um for 1 mm diameter device). A solid to liquid phase change of trapped paraffin into the PDMS is used ...

Silicone elastomer stamp with hydrophilic surfaces and method of making same

Heiko Wolf, Bruno Michel, Emmanuel Delamarche, Christian Donzel

A method for fabricating silocone elastomer stamps with hydrophilic surfaces is provided. The concept of polymer grafting is used to produce the stamps. The stamps thus produced have the great advantage that grafting of a thin hydrophilic polymer on a hydr ...

Holographic recording in a photopolymer by optically induced detachment of chromophores

Demetri Psaltis

We demonstrate holographic recording in a new photopolymer system. The recording material is created by copolymerization of an optically inert monomer, methyl methacrylate, and a second monomer that is optically sensitive. On exposure of the recording mate ...
