Poly(vinylidene fluoride)(PVDF) has been studied as a representative piezoelectric polymer exhibiting the largest permittivity. However, the piezoelectric material using only PVDF has a relatively low mechanical properties. In this study, PVDF having piezoelectric property and highly oriented liquid crystal polymer polyarylate(PAR) were blended to prepare a filament, and piezoelectric composites were prepared by fused deposition modeling(FDM) type 3d printing using filament. The composites were prepared through various conditions of blend ratio, printing temperature and speed and the changes of physical properties were confirmed by analyzing the composite materials. |
