Preparation of Flexible Nano Piezoelectric/Glass Fiber Cloth Composite by Hydrothermal Method

摘要

Flexible Nano PZT/GFC piezoelectric composite material is pliable and tough. It has potential application prospect on the piezoelectric sensors or drives, especially used for complex surface condition fitly. The composite material was prepared by growing the PZT piezoelectric nanocrystals on the glass fiber cloth (GFC) using the hydrothermal method. The influences of hydrothermal reaction time, concentration of alkali, and the number of glass cloth on the preparation of the piezoelectric composite material were investigated. It was found that a lot of PZT nanocrystals grew intensively and firmly on the soft glass fiber cloth carrier. The quantity of the glass fiber cloth affected the PZT nanocrystalline synthesis, the crystallization performance of product decreased sharply with the number of the glass fiber cloth added. Cubic PZT nanocrystals are formed when the concentration of KOH is 10 mol/L and the reaction time is 72 h.
