英文摘要： At present, the research of piezoelectric nanogenerator has become one of the front and hotspot tasks in the international nanomaterials research field. It not only has both significant theoretic values and wide potential applications, but also is a certain challenge task. Based on the piezoelectric composite nanowire arrays, this project will carry out the systematic and basic research including preparation techniques, composition design, the assembling techniques and the measurement of properties for piezoelectric nanogenerator. We will study the following four key scientific problems, such as the tuning growth of the piezoelectric composite nanowire arrays and its growth mechanism, the relationship of structural design, assembling techniques and properties, the relationship between composition mechanism and piezoelectric property, and based on the theoretical simulation of the piezoelectric output mechanism, effective methods and approaches to improve piezoelectric property. This work has novelty for the piezoelectric composite nanowire arrays nanogenerator, growth mechanism, piezoelectric composition mechanism, and improved properties. It is expected the present research may offer useful guidelines to the design and application of piezoelectric composite nanomaterials and devices.
