Anti-corrosion peptide coatings and laser patterning for application on flexible transparent silver nanowire electrodes

This work describes physicochemical processing strategies to allow the efficient use of oligoglycine-based coatings for corrosion protection of transparent silver nanowire (AgNW) electrodes fabricated on flexible polyethylene terephthalate (PET) substrates. The peptide anti-corrosion coatings consis...
