Green conductive flexible printing inks already available with low sheet resistivity (<20mW/sq/ 25µm), and no modification of electrical conductivity neither plastic deformation of polymeric film samples observed for strains <8% (UNE-EN ISO 527-3/AC:2002). Applications on flexible substrates such as polymeric films (PET, PC), textiles (woven, knitted, nonwoven), laminates, paper/cardboard, and leather are possible. Industrial sectors: textile, paper, packaging, automotive, and energy sectors.
