The preparation research of inorganic hollow nanospheres

探索新的纳米结构已成为近年来物理、化学、材料等领域的研究热点之一。纳米空心球作为一种新的纳米结构,其特有的核-壳空心结构及纳米厚度的壳层使它具有许多优异的物理化学性能,从而在医学、制药学、材料学、染料工业等领域具有很好的应用前景。本文综述了模板法和由模板法发展而来的L-b-L自组装法制备无机材料纳米空心球的一般过程及原理,最后展望了纳米空心球材料的发展前景,并探讨了目前在无机材料纳米空心球研究领域中存在的问题。

The unique core-shell hollow morphology and the nanoscaled shell have made hollow nanosphere widely used in medicine, materials and dye industries. Thus the preparation of hollow nanosphere has been a crucial problem in the research of this new nanostructure. In this paper, several methods for the preparation of inorganic hollow nanospheres have been presented and evaluated. The application prospect of hollow nanospheres and the problems existing in current research of inorganic hollow nanospheres were also discussed.
