Presentation Summary

Arjowiggins developed a unique and biodegradable paper that enables to print smart objects on it. The main characteristics are:
  • A closed and very smooth surface (down to 10 nm in Ra using AFM)
  • A high temperature resistance for efficient sintering (between 160 to 200 °C during 5 minutes).
  • A right Free Surface Energy (40-50 mJ/m²) for good ink adhesion.
  • Carried out printing trials with different processes (inkjet, silk screen, flexo, CVD + laser ablation) and we manufactured smart objects like resistors, capacitors, antenna and circuitry on our paper.
  • Achieved a low resistivity with a low ink thickness (100 mΩ/sq resistivity for 1,5 µm thick Ag-ink) and CVD coupled with a laser ablation process allowed us to manufacture 5 µm wide circuitry on gold.
