IPF at DESY: Investigations of structure formation in polymers

Challenging but successful days for scientists (Eric Euchler, Anna Sambale, Regine Boldt, Enno Henn, Sitao Wang, Lutz Zybell, Kai Uhlig) from the Institute of Polymer Materials (headed by Prof. Markus Stommel) of the IPF at DESY P03 beamline.

For the first time, the FlowCell device developed at the IPF was used in combination with a conventional single-screw extruder at the MiNaXS beamline P03 to investigate the crystallization kinetics during the solidification of processed iPP, PA6 and PLA melts. The experiments could only be performed remotely, consequently, the FlowCell and extruder control had to be fully integrated into the instrumentation of the beamline.

The conducted experiments are part of the IPF-DESY Long-Term Project (LTP, no. II-20220003) to develop an experimental setup for in situ investigations of (micro)structure formation in polymers (transcrystalline structures, flow-induced crystallization, phase separation) under defined process conditions that are typical and relevant for common melt processing technologies such as extrusion or injection molding.

The IPF scientists would like to thank Matthias Schwartzkopf and Sarathlal Koyiloth Vayalil for the excellent support at the beamline and the team of IPF Research Technology (Forschungstechnik) for the technical implementation of the research ideas.

Aachen Summer School: Textiles become smart through 3D printing and origami

From 21 to 29 September 2026, the Aachen Summer School will transform Institut für Textiltechnik (ITA) of RWTH Aachen University into a laboratory of the future: over the course of a week, students will use origami folding techniques and 3D printing to develop active textile structures capable of performing programmable movements. This interdisciplinary event combines theoretical foundations with practical prototyping – from digital modelling right through to functional textile prototypes.

25 years of medical devices: ITVP combines experience with innovation

ITV Denkendorf Produktservice GmbH (ITVP) is celebrating its 25th anniversary. On October 1, 2001, ITVP was founded as a subsidiary of the German Institutes of Textile and Fiber Research Denkendorf (DITF), Europe’s largest textile research center. This spin-off company made it possible to consolidate expertise in medical technology and significantly expand production, which had previously been initiated mostly in the DITF’s cleanrooms.

An eco-friendly alternative to fluorocarbon treatments

Protective and outdoor clothing derives its durable water-, dirt- and oil- repellent properties from the application of fluorinated polymers or per- and polyfluorinated low-molecular- weight chemicals (PFCs). The beneficial properties thus achieved on textiles are offset by environmental and human health risks. For manufacturers of sports, medical, protective and automotive textiles, researchers at the Sächsisches Textilforschungsinstitut e.V. and the Leibniz Institute for Polymer Research have developed liquid-applied dispersions and solutions to functionalise textiles without the use of fluorine.
