纳米材料原位生长表征技术的研究进展

Progress in Characterization Technique of In-Situ Growth of Nanomaterials

纳米技术的关键是按人们的意志直接操控单个原子、分子或原子团、分子团,实现纳米材料的可控合成,制备具有特定功能的材料。纳米材料原位生长研究可获得体系中纳米粒子生长过程的动态瞬时信息,继而掌握纳米材料生长特征模式和生长参数,该研究对实现纳米材料可控生长具有重要意义,本文就纳米材料原位生长研究的技术方法进行概述,并对其发展前景进行展望。

The key of nanotechnology is operating single atom, molecules or the groups of atoms and mole-cules directly according to the aspiration of the people, realizing the controlled synthesis of na-nomaterials and synthetizing materials with specific functions. In-situ growth research of nano-materials can obtain the dynamic transient information of the growth process of nanoparticles in the system, and then grasp the growth characteristic and parameters of nanomaterials. It is significant for controllable synthesis of nanomaterials. In this paper, many different technical approaches which can be applied to trace the in-situ growth of nanomaterials are summarized, and the development prospect was forecasted.
