Classical shape-memory polymers are heat-shrinkable materials, which are of technological significance as packaging material or assembly materials in electronics. Their one-way recovery effect allows a programmed material to recover a permanent shape upon exposure to heat. Various stimuli besides temperature changes have been realized in polymer-based materials for inducing SME and several consecutive shape-changes could be implemented in one material resulting in multi-shape materials. Recently, shape-memory polymer actuators were introduced allowing reversible shape-changes controlled by temperature or magnetic fields. The general principles for programming polymers to exhibit shape recovery or actuation behavior will be explained and potential applications are outlined including healthcare technologies and rebotics.
ABOUT THE SPEAKER
Andreas Lendlein received his doctoral degree in Materials Science from Swiss Federal Institute of Technology (ETH) in Zürich in 1996. He worked as a visiting scientist at the Massachusetts Institute of Technology in 1997-98 and completed his habilitation in Macromolecular Chemistry in 2002 at the RWTH Aachen University. Since 2002 he is institute director at the Helmholtz-Zentrum Geesthacht in Teltow and Professor for Materials in Life Sciences at the University of Potsdam, Germany. Furthermore, he is honorary professor in Chemistry at the Freie Universität Berlin and member of the medical faculty of Charité University Medicine Berlin. His research interests in material science & engineering are creation of material functions by design and implementation of multifunctionality in polymer-based materials with special emphasis given to stimuli-responsive polymers, especially shape-memory polymer actuators, biopolymer-based material systems and structured biomaterials. He also works on fabrication schemes for multifunctional materials including integrated processes and advanced manufacturing methods as well as on studies related to processes occurring at interfaces, e.g. biointerface or water/air interface. Biomaterial-based regenerative therapies, controlled drug delivery systems, health technologies and robotics recently are his interests in translational research. Andreas Lendlein published more than 500 peer-reviewed papers (H-factor: 55), is an inventor on about 300 issued patents and published patent applications, and received more than 20 awards for his scientific work and his achievements as an entrepreneur including the BioFUTURE Award, Hermann-Schnell Award, and the World Technology Network Award in the category Health & Medicine. He is founding Editor-in-Chief of the journal Multifunctional Materials (IOP Publishing) and serves on the Executive Advisory Board of VCH-Wiley´s Macromolecular Journals.
