摘　　要：微米管作为一种新型的准一维结构材料,由于其独特的结构-性能特征及其在物理电子学、光学、生物医学、化学、材料学和微电机系统等领域具有广阔的应用前景,而深受研究者的广泛关注。该文系统地论述了微米管的主要化学制备方法,包括直接气相沉积法、层状结构卷曲法、模板辅助法、金属辅助催化法和热溶液法等及其对应的生长机制,指出了各种制备方法的优、缺点,并概述了微米管的应用进展。As a new kind of quasi one-dimensional materials, microtubes have attracted extensive investigations in recent years, due to their unique structure-property characteristics and potential applications in physical electronics, optics, biomedicine, chemistry, materials science, and micro electronic mechanical system （MEMS）. The present paper provides an overview on the research progress of the chemical techniques including vapor phase direct deposition method, lamella structure scroll method, template-assisted method, metal-catalyst-assisted method and thermal solution method, and the corresponding growth mechanism for the synthesis of microtubes, presents a brief remark on the specific merits and the inevitable weakness of each synthesis techniques, and finally summarizes the application progress of microtubes as well.
