无铅柔性压电复合材料进展

Recent Advancement of Lead-free Flexible Piezoelectric Composites

压电复合材料是20世纪70年代发展起来的一种多用途功能复合材料。由于环保、材料使用性能和器件形态与成型工艺要求的提高,对无铅,超薄型、异型、大面积可柔性加工的压电复合材料的研究已成当务之急。从压电复合材料的基本概念、结构与性能关系,特殊加工工艺设计需要等出发,在总结回顾压电复合材料进展的基础上,综合相关学科的理论与实践新成果,对如何开拓新型无铅柔性压电复合材料与技术进行了综述。引用文献19篇。

As a multipurpose functional material,inorganic/polymer hybrid piezoelectric composites have been developed since the 1970s.According to the consideration of environment protection regulations and property/processing requirements,the study of lead-free flexible piezoelectric composites is in urgent need.In this paper,start with the fundamental conceptions,development,factors influencing the properties,recent status and prospects are reviewed with 19 refs.
