POROUS PIEZOELECTRIC COMPOSITES AND PRODUCTION THEREOF

This abstract first appeared for US patent application 20250018642 titled 'POROUS PIEZOELECTRIC COMPOSITES AND PRODUCTION THEREOF

Original Abstract Submitted

parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component present therein. printed parts having piezoelectric properties may be formed using compositions comprising a plurality of piezoelectric particles dispersed in at least a portion of a polymer matrix comprising first polymer material and a sacrificial material, the sacrificial material being removable from the polymer matrix to define a plurality of pores in the polymer matrix. the piezoelectric particles may remain substantially non-agglomerated when combined with the polymer matrix. the sacrificial material may comprise a second polymer material. the compositions may define a composite having a form factor such as a composite filament, a composite pellet, a composite powder, or a composite paste. additive manufacturing processes may comprise forming a printed part by depositing the compositions layer-by-layer and introducing porosity therein.
