Title:
COMPOSITION FOR PIEZOELECTRIC ELEMENT PRINTING, METHOD FOR PREPARING SAME, AND PIEZOELECTRIC ELEMENT PRINTER USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/018009
Kind Code:
A1
Abstract:
The present invention relates to a composition for piezoelectric element printing to form a piezoelectric element by constructing a DLP-based real-time poling process system, a method for preparing same, and a piezoelectric element printer using same. The present invention comprises the steps of: adding, to a solvent, PVDF-HFP formed by copolymerizing polyvinylidene fluoride (PVDF) and hexa fluoropropylene (HFP), followed by stirring; adding a photo-curable polymer to the stirred solution; degassing the solution added with the photo-curable polymer, thereby preparing a composition for piezoelectric element printing.
