Enthalpic, entropic, and square gradient contributions to the surface energetics of amine-cured epoxy systems

The evolution of surface tension during polymerization of three amine-cured epoxy systems was investigated. Due to the chemical reaction of the epoxy groups with primary and secondary amines, the energetic status of an epoxyamine system increased during p ...

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 ...
