【摘要】：在生物电体系中,细胞膜中层级排列的离子通道和离子泵构成集成化的纳米尺度的离子导体,它们成为生命体系能量转换的关键结构基础.从生物离子通道上获得相关启示,通过构筑一维、二维纳米孔道来模拟生物离子通道的结构和功能,实现了可控的离子传输和能量转换.本文总结了仿生离子通道从一维直通构型到二维层状构型的发展,各自的特点、材料的制备方法,以及在仿生能量转换方面的应用.二维仿生离子通道提供了一种大规模、低成本、更为高效的纳米孔道材料制造技术,向纳米孔道材料的实用化迈出了重要一步.本文还重点介绍了二维层状材料及其构筑的二维离子通道在超滤、能量转换与存储等方面的应用.
[Abstract]:In bioelectric systems, ion channels and ion pumps arranged at different levels in the cell membrane form an integrated nanoscale ionic conductor, which becomes the key structural basis for energy conversion in biological systems. The structure and function of biological ion channels are simulated by constructing one dimensional and two dimensional nanorods to achieve controllable ion transport and energy conversion. In this paper, the development of bionic ion channels from one dimensional straight through configuration to two dimensional layered configuration is summarized. Two dimensional bionic ion channels provide a large scale, low cost and more efficient fabrication technology for nano-porous materials. This paper also focuses on the application of two-dimensional layered materials and two-dimensional ion channels in ultrafiltration, energy conversion and storage.
