英文摘要：

As a unique natural silicate mineral fiber,chrysotile has many properties like nano hollow tubular structure,high surface chemical activity and biological activity.It is widely concerned and researched in the field of controlling environmental pollution and nanomaterials preparation.One-dimensional quantum dots and quantum wires can be prepared by using chrysotile nanotubes as templates;the one-dimensional silica prepared after acid corrosion can also be used as carriers in synthetic one-dimensional nanocomposites,which will be widely used in catalytic,optoelectronics,and other aspects.It is very important to research on its nanotube and the physical and chemical properties,in order to utilize its uniform tubular structure and stable physical property,which has a very important practical significance for the development of natural nano-materials.
