Embodiment

[0075] combination:

[0076] The ferroelectric ink compositions in the examples comprise thermoplastic polyurethane (Estane 5719 from Lubrizol) or phenoxy resin (PKHJ from IncChem) dissolved at levels ranging from 10% to 50%, preferably 25%. in DBE-9), or Superglue3 from Henkel dissolved in 2-butoxyethyl acetate (BCA).

[0077] The ferroelectric ink compositions of the examples comprise an organic ferroelectric component such as poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) from Solvay.

[0078] Solvents used in these systems include acetone, methyl ethyl ketone (MEK from Alfa Aesar), N,N-dimethylformamide (DMF from Alfa Aesar), and DBE-9 (from Sigma-Aldrich).

[0079] To prepare ferroelectric inks, ferroelectric components and inks are mixed together in different procedures depending on the chosen system.

[0080] In Table 1, detailed compositions of Examples 1 to 6 are shown.

Abstract

The present invention relates to a printable ferroelectric ink composition comprising a binder, an organic ferroelectric component and a solvent, and wherein said ferroelectric component is in the ferroelectric phase. The ferroelectric ink composition according to the present invention can be used as a sensor, an emitter or as a generator in an energy harvester. Furthermore, the present invention also encompasses a device comprising a ferroelectric ink composition according to the present invention between two conductive elements.

Description

technical field [0001] The invention relates to a printable ferroelectric ink composition. The compositions of the present invention exhibit adhesive properties while maintaining good ferroelectric response. Background technique [0002] Currently, applications where ferroelectric materials are required use ferroelectric ceramics or ferroelectric polymers. The latter exhibited very low adhesion, while the former showed no adhesion at all. Therefore, if these materials must be permanently fixed to any substrate, an adhesive layer must be used to bond them. [0003] For example, ferroelectric ceramics have been mixed with polymer resins, resulting in composite materials. This method is widely used and well known; however, polymer resins are used not for their adhesive properties but for their binding properties. By doing so, the mechanical properties (too brittle) and processability (often difficult to process) of ferroelectric systems are improved. [0004] For example, ...
