项目摘要

This work demonstrates thermal-to-electric energy conversion based on ionic nanofluidic transport in nanochannels inducted by a temperature gradient. Two types of highly periodic and high aspect ratio nanochannels have been fabricated in a silicon (Si) substrate and in an aluminium oxide (Al2O3) membrane. Silicon nanochannels with diameter of 100 nm and height of 300 μm have been produced by metal-assisted chemical etching process (MACE), while nanochannels with the dimensions of the 10 nm and 3 μm respectively, were fabricated in a Al2O3 membrane by the anodic aluminum oxidation (AAO) process. Moreover, a novel approach of thermally nanofluidic energy harvesting was proposed and conducted.

这项工作演示了基于离子纳米流体在纳米通道中通过温度梯度诱导的热能到电能的转换。两种类型的高周期性和高纵横比的纳米通道已被制造在硅（Si）基板和氧化铝（Al 2 O 3）膜。采用金属辅助化学腐蚀（MACE）工艺制备了直径为100 nm、高度为300 μm的硅纳米通道，采用阳极铝氧化（AAO）工艺在Al2O3膜上制备了直径为10 nm、高度为3 μm的硅纳米通道。此外，提出了一种新的方法，热纳米流体能量收集。
