Description
Biological systems found in nature exhibit highly complex hierarchically ordered 3D structures with many degrees of organization and functionalization to achieve their unique mechanical and biological properties. While biological systems grow theses anisotropic reinforcement architectures, the fiber alignment in polymer processing and especially 3D printing requires external forces such as shear force, electric – or magnetic fields and is often limited to specific scenarios.[1]Herein, the research results for a nanofiber alignment technology transferable to extrusion-based 3D printing employing electrical fields is reported. Using optical microscopy and a specially designed flow cell, we were able to measure and visualize the competition between the alignment due to uniaxial shear forces and the alignment due to the imposed electric field perpendicular to the flow direction. With this proof-of-concept study a European patent application was filed.[2]
