Meter‐Long and Robust Supramolecular Strands Encapsulated in Hydrogel Jackets

Jacketed supramolecular strand: Meter-long supramolecular strands were obtained by encapsulating them in polymer gels using a microfluidic channel (see picture). The nanofibers in the strands are self-assembled and aligned under the laminar flow conditions. Their mechanical strength was sufficiently high to allow their patterning onto a substrate and use them as a template for synthesizing an insoluble, conductive polymer.
