Abstract

Piezoelectric ceramics, lead zirconate titanate (PZT), have been widely used for sensors and actuators due to their high electromechanical properties. However, the brittle nature of ceramics limits their applications to only small deformations as the flexibility and durability of these materials are the main essential factors required for practical applications. The flexible piezoelectric materials can be developed by blending PZT with flexible polymeric materials such as nanocellulose fibers. The bio-based nanocellulose fibers (CNF) have been reported as a type of electroactive polymer with a piezoelectric response exhibiting excellent mechanical strength and modulus. In this regard, the present study focuses on enhancing the mechanical strength and load-bearing capability of PZT by blending 20 and 30wt% of PZT powder with 80 and 70wt% CNF to obtain a flexible piezoelectric composite film via 3D printing. The 3D printed films' structural, morphological, and mechanical properties were investigated through XRD, SEM, and tensile tests. The SEM images and XRD analysis demonstrated that the PZT powder was uniformly dispersed in the CNF films and showed the morphotropic phase boundary (MPB) in PZT/CNF films. The addition of CNF in PZT has improved the mechanical strength significantly.
