It's enough to make your head spin!
The Leibniz Institute for New Materials (INM) is at HANNOVER MESSE 2018 to unveil a new electrospinning process. This involves linking fine fibers so that invisible touch control areas can be added to curved surfaces.23 Apr. 2018
"What's innovative about our technology is the starting materials we use. We process polymers and composites but also sols, which are then calcined. Depending on the starting material, it's possible to produce both intrinsically conductive fibers and those that become electrically conductive in a further step via silvering," says Peter William de Oliveira, Head of the InnovationCenter at the INM. Unlike previous patterning processes such as stamping and printing, electrospinning produces unstructured conductive fleece, whose density is high enough to enable electrical conductivity across the whole of the substrate. At the same time, the number of fiber intersection points is so low that light scattering is reduced to less than two percent. With fibers that are 100 times thinner than a human hair, the fleece is invisible to the human eye and appears transparent. The fleece's net-like, asymmetrical structure also eliminates typical diffraction phenomena, such as distracting rainbow effects.
