Feature Publication: Surfx plasmas improve adhesion in flexible electronic devices

Professor Rahul Panat and coworkers at Washington Sate University have recently reported on highly stretchable metal interconnects for flexible electronic devices. They have used advanced fabrication techniques to deposit thin metallic films onto elastomers, for example, an indium and chromium bilayer on polydimethylsiloxane (PDMS). A key step in the process is treating the elastomer with the AtomfloTM atmospheric pressure plasma system. This improves chromium adhesion to the PDMS, so that the material can undergo repeated stretching without delamination. Adhesion of 3D structures to flexible polymer substrates is an enabling technology in the development of “smart” wearable electronics. A sampling of publication titles by Professor Panat’s group at WSU is listed below.
