Summary: | Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component. Printed parts having piezoelectric properties may be formed using compositions comprising a plurality of piezoelectric particles non-covalently interacting with at least a portion of a polymer material via π-π bonding, hydrogen bonding, electrostatic interactions stronger than van der Waals interactions, or any combination thereof. The piezoelectric particles may be dispersed in the polymer material and remain substantially non-agglomerated when combined with the polymer material. The polymer material may comprise at least one thermoplastic polymer, optionally further including a polymer precursor. The compositions may define an extrudable material that is a composite having a form factor such as a composite filament, a composite pellet, a composite powder, or a composite paste. Additive manufacturing processes using the compositions may comprise forming a printed part by depositing the compositions layer-by-layer. |
