Abstract
Problem statement: Perovskite lead zirconate exhibits in an orthorhombic formation at a temperature below the Curie temperature, TC. Approach: The orthorhombic is non-centrosymmetric which is capable of spontaneous polarization (electronic, ionic and orientation), depending on their composition and volume fraction. Results: The results from FTIR spectroscopy, XRD patterns, and SEM indicate that the lead zirconate particles are dispersed in Acrylic Rubber (AR72) matrix. At a small amount of lead zirconate particulates present in the AR72 matrix, at nearly 0.3986% V/V (AR72/PZ_5), the electrical conductivity increases dramatically by two orders of magnitude. Conclusion/Recommendations: Our synthetic Rubber (AR72)/lead Zirconate (PbZrO3) composite materials can be successfully used as the candidate materials of soft Electroactive (ER) actuators, sensors, artificial muscles, and smart engineering devices.

Lead Zirconate (PbZrO3) and Acrylic Rubber (AR72) composite materials can be used as biomimetic actuators, artificial muscles and smart engineering devices such as active engine mounts, shock absorbers, clutches, brakes, damping devices, hydraulic valves and robotic controlling systems (Dias and Das-Gupta, 1996; Shiga, 1997)
Summary
Composite materials are made of a filler (either particles, flakes or fibers) embedded in a matrix made of polymer, metal and ceramic and composed of any material consisting of two or more distinct phases. Combining a ferroelectric ceramic and a polymer host to form a flexible ferroelectric composite has been pursued in recent years in view of the greater flexibility allowed by these materials to suit particular property requirements such as mechanical, electrical, thermal and/or a coupling between these properties. The by SEM, FTIR and XRD to confirm the electrical property results. The electrical properties of both filler and matrix are important in determining applications. Characteristics of the ceramic powder depend on their composition and their crystal structure and
