Dirk J. Broer, Professor at Eindhoven University of Technology, will be presenting during the 4D Printing & Metamaterials Conference: “Morphing dynamics in light-triggered liquid crystal networks”.
Polymers that can change shape or their surface topography in a programmed way have a wide application potential varying from micro-robotics to avionics. We developed morphing principles based on liquid crystal networks. The triggers are temperature, light, pH or changes in environment. The focus of the lecture is on UV actuation of surfaces. Accurate positioning of molecules in a thin layer predetermine the deformation figures. The surface topographies are dynamic and disappear as soon as the light is switch off. An interesting feature is that the surface tribology can be altered be UV exposure.
