Reversible photo-patterning of soft conductive materials via spatially-defined supramolecular assembly

A strategy for reversible patterning of soft conductive materials is described, based upon a combination of peptide-based block copolymer hydrogelators and photo-thermally-active carbon nanotubes. This composite displays photo-responsive gelation at application-relevant timescales ( 100 S m−1), which, additionally, hold the capability to revert to sol upon sonication for reprocessing.
