Piezoelectric materials are featured by their property to create potentials against mechanical stimulations such as compression, extension, and vibration. Barium titanate (BaTiO3) with a perovskite structure is an lead-free inorganic piezoelectric material with a high piezoelectric coefficient of ~260 pC/N. Since cellulose is the most abundant natural polymer on earth and has a piezoelectric coefficient of ~6 pC/N, it is considered as an attractive substrate for paper-shaped piezoelectric elements. In order to investigate eco-friendly piezoelectric materials, in this study, we have fabricated a series of piezoelectric composite papers via electrospinning of cellulose solution including BaTiO3 nanoparticle. SEM and XRD patterns are obtained to identify the dispersion and crystalline features of BaTiO3 in the cellulose-based composite papers. In addition, the piezoelectric performance of the cellulose composite papers investigated under periodic compression and bending deformations. |
