A primer layer comprising a polyvinyl butyral resin enhances adhesion of silver nanoparticle inks onto plastic substrates. The primer layer comprises a polyvinyl butyral (PVB) resin having a polyvinyl alcohol content between about 18 wt. % to about 21 wt. %. The PVB resin may also have a glass transition temperature greater than about 70° C. Optionally, the PVB primer layer may further be enhanced by cross-linking using a melamine-formaldehyde resin. Conductive traces formed on plastic substrates having the PVB primer layer exhibit an acceptable cross-hatch adhesion rating with little to no degradation of adhesion being observed after exposure to 4-days salt mist aging or 1-day high humidity aging.

The present invention relates to a process of fabricating P(VDF-TrFE) films by modifying the solvent composition. Two solvents MEK and DMSO were mixed in pre-determined ratios and that co-solvent mixture was used for fabricating the P(VDF-TrFE) films. By virtue of such method driven P(VDF-TrFE) films, the ferroelectric capacitors comprising of the same were found to achieve low voltage operation, thermal stability and fatigue endurance, which indicated improved ferroelectric performance of the devices. In addition, the films made by same process also yielded high piezo- and pyro-electric coefficient, indicating improved piezo- and pyro-electric performances of the devices.
