Abstract
The invention deals with a method of bonding a poly(vinylidene fluoride) solid to a variety of solid substrates, in an application typically using the piezoelectric properties of the material. The bonding method entails surface preparation of the poly(vinylidene fluoride) by a variety of steps including activation of the surface by plasma etching to cause the surface to wet the adhesive used in the bonding process. The bonding method produces bonds of increased strength and having good electrical properties.
