微纳复合结构中金属液体填充物的电致力效应的原位研究

申请人(Y.H. Gao)在金属Ga、In填充纳米管方面做出了系统的温度测量研究工作，并发现了电子束辐照下氧化硅微球壳-纳米管中填充物金属Ga的电液压膨胀效应，观察了Ga在纳米碳管中的电驱动。本基金拟在这些基础上，主要研究微纳复合结构中金属Ga、In液体填充物的电致力效应，研究微纳尺度下力量的产生与传递机理，研究液体在电流、电场作用下的原位运动，驱使液体填充物进行周期性运动，研究周期性运动的产生机制, 研制液压媒介(hydraulic)的微纳电驱动传动机械(HMNEMs)单元。这些基础前沿性的研究为微纳电驱动液体传动机械的应用提供丰富的素材和原始模型，促进微纳电驱动液体传动机械成为现实做出奠基性工作。

The applicant (Y.H. Gao) has finished systemic research works on Ga/In filled nanotubes for temperature measurement, also found an abnormal expansion effect: Electron-beam induced electric-hydraulic expansion in a silica shelled gallium microball-nanotube structure, as well as observed the electrically driven gallium movement in carbon nanotubes,which can be used for nanomass delivery and nanoswitch. Based on the above mentioned research results, this proposal will study the mechanism of electricity induced forces on Ga/In liquid filling in micro-nano hybrid structure, the generation and transformation mechanism of the forces, the in-situ movement of Ga/In liquid filling under current and/or electric field, the generation mechanism of periodic movement, and at last fabricate a hydraulic micro-nano-electromechanical system (HMNEMs) unit. This basic and frontier reasearch will provide us abundant original information and model for HMNEMs'applications,give us a foundation to improve the HMNEMs into real applications.
