Fabrication of Ultraviolet-Curable Piezoelectric Composite for Sensor and Actuator Applications

In this work, we give a detailed examination of the development of a new piezoelectric ceramic-polymer composite. A full account of the major methods developed in making the polymer composite is presented. Norland Optical Adhesive 65 (“NOA65”) is an ultraviolet (UV)-curable adhesive with potential to be used as a functional material in stereolithography additive manufacturing. The salient aspects of processing such a composite is summarized. This involved preparing samples by using the spin coating technique. Samples of the composite mixture are spin coated on silver-coated glass slides at 2000 rpm for 10s to give a layer thickness of 100μm. The average $\pmb d_{33}$ of the composite material was measured and shown to be 2.8 pm/V.
