Ferroelectric capacitor with improved fatigue and breakdown properties

A ferroelectric material consisting of a polymer blend of at least two polymers, wherein the first polymer is a ferroelectric polymer and the second polymer has a low dielectric constant,

• wherein the second polymer is a polyphenylene ether having the following structure:
• wherein the oxygen ether atom of one unit is connected to the benzene nucleus of the next adjoining unit,
• R1 and R2 are each individually a hydrogen, a halogen, a hydrocarbon radical, a halohydrocarbon radical having at least two carbon atoms between the halogen atoms and the phenyl nucleus, a hydrocarbonoxy radical, a halohydrocarbonoxy radical having at least two carbon atoms between the halogen atom and the phenyl nucleus, or a substituted or unsubstituted phenyl group, and
• wherein the polymer blend comprises a crystalline or semi-crystalline polymeric matrix of the ferroelectric polymer and a plurality of amorphous nanostructures comprising the second polymer, wherein the plurality of amorphous nanostructures are comprised within the polymeric matrix, and wherein the polymer blend comprises 1 to 8 wt. % of the second polymer.
