SPP 1369:  Polymer Solid Contacts: Interfaces and Interphases

• Subject Area: Chemistry ; Mechanical and Industrial Engineering
• Term: from 2008 to 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 45258051

The focus of the Priority Programme is the investigation of dense amorphous polymer phases at or near a solid surface. Particular attention is given to the so-called interphase, i.e. the region of the polymer phase where its properties have not quite reached their bulk values. The thickness of the interphase depends not only on the type of polymer and solid and on their interactions, but also on the property under investigation. The mass density, for example, reaches its bulk value much earlier than the cross-link density of a reactive system.
Polymer-solid contacts play an important role in technology, from adhesion and coatings to nanocomposites. Yet, the research of the Priority Programme is aimed at the fundamental understanding of the interface and interphase, and not at particular material combinations for particular applications. The investigations are to be carried out using modern methods of preparation, characterisation and theory.
