Metastable Packaging For Transient Electronics
Abstract
Metastable polymeric materials were synthesized, formulated with additives and microcapsules, and then processed into films that served as substrates on which electronic devices were fabricated. New to this effort was the intentional development of depackaging cascades -- the rational design of materials that depolymerize on exposure to specific stimuli. In particular, we investigated acid-sensitive, depolymerizable poly(phthalaldehyde) (PPA), and thermally- and base-sensitive poly(olefin sulfone) (POS) polymers. Conditions for film preparation and fabrication of transient electronics on robust PPA and POS films were optimized. Three degradation triggers -- direct activation by photoacid generation, thermal activation, and mechanical rupture of acid-filled microcapsules -- were investigated.
