  4. Adhesion Failure of Ink on Plastic Films • Adhesion: a measure of the strength of bonds between the ink and plastic substrate through the interface. • Adhesion Strength Test: The Nano Indenter (MTS) witha conical-shaped diamond tip (90, radius: 1mm) is used to scrape the surfaces of the samples under an increasing normal force The critical forces, at which the interface failed and the ink was peeled off the plastic film, reflects the adhesive strength.

  5. I II III IV V Different configurations of adhesion failure

  6. a b c d A SPM analysis of adhesion failure (a) 2-D color-scaled topographic image of a scratch made under an increasing force from 2.9mN to 3.1mN at the surface of an ink sample. (b) Profile along the bottom of the ditch. (c) 3-D view of the topographic image. (d) Lateral force image taken simultaneously with the topographic image.
