Facile preparation of high loading filled PVDF/BaTiO₃ piezoelectric composites for selective laser sintering 3D printing.

ABSTRACT: 3D printed piezoelectric devices, due to their sufficient multidimensional deformation and excellent piezoelectric properties, are one of the most promising research directions. However, the lack of high loaded piezoelectric composites is the key bottleneck restricting the enhancement of the piezoelectric output. In this work, we successfully prepared a novel high loaded polyvinylidene fluoride (PVDF)/barium titanate (BaTiO₃) piezoelectric composite suitable for selective laser sintering (SLS) 3D printing via solid state shear milling (S³M) technology. The 50 wt% BaTiO₃ filling made the most outstanding contribution to the piezoelectric properties of the composites. The 3D printed cymbal parts with a stress amplification effect exhibited outstanding
