It has also been found that PLZT ceramics are near ideal for achieving the ultra-high displacements recently reported for the Rainbow (Reduced and INternally Biased Oxide Wafer) actuators. In order to determine the optimum composition or compositions for these Rainbow actuators, a study was conducted by preparing and processing selected formulations throughout the PLZT system. Results from this study indicate that, like the conventional direct extensional-mode materials, the maximum Rainbow bending displacements occur in materials located compositionally at the morphotropic (FE/sub rhomb/-FE/sub ter/) and Curie point (FE-PE, PE-AFE) phase boundaries. Examples of specific compositions for each of these regions are 2/53/47, 9/65/35 and 8.5/70/30 (La/Zr/Ti), respectively. Microstructural (grain size), electrical (dielectric constant, dissipation factor) and electromechanical (axial displacement) data are presented for selected compositions in the system.","PeriodicalId":20488,"journal":{"name":"Proceedings of 1994 IEEE International Symposium on Applications of Ferroelectrics","volume":"103 1","pages":"313-318"},"PeriodicalIF":0.0,"publicationDate":"1994-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87067717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two sets of nylon 11 film samples were produced. The first set was melt-quenched and poled, while the second set was melt-quenched and then cold-drawn at room temperature before poling, resulting in a three-dimensionally ordered sample. Gold electrodes, 10 mm by 10 mm, were evaporated on opposing sample surfaces. The remanent polarization of the unoriented sample was 27 mC/m/sup 2/ while that of the oriented sample was 52 mC/m/sup 2/. Samples of each film were placed in a programmable environmental chamber and connected to a Hewlett Packard 4195A Network/impedance Analyzer via a custom remote fixture. Broadband measurements were made of the clamped capacitance and dissipation factor, thickness-mode electromechanical coupling coefficient k/sub t/, mechanical quality factor Q/sub m/, and longitudinal sound velocity v/sub l/ for each sample over a temperature range of 20/spl deg/-160/spl deg/C. Comparisons of the properties were made between oriented and unoriented film samples. The results showed k/sub t/ values in the 0.03-0.11 range, and Q/sub m/ values of 8-10 above the glass transition temperatures of the samples (approximately 60-70/spl deg/C). The results show promise for high temperature ferroelectric nylon sensing applications.","PeriodicalId":20488,"journal":{"name":"Proceedings of 1994 IEEE International Symposium on Applications of Ferroelectrics","volume":"35 1","pages":"337-340"},"PeriodicalIF":0.0,"publicationDate":"1994-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86624489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
