Silica Nanofibers Enwrapped with Well-organized AgCl Nanoparticles

介绍了一种通过静电作用合成AgCl-SiO2复合材料的新方法. 这种方法能够制备出线条均匀的纳米二氧化硅纤维,直径范围在30~100 nm,纤维的长度大于20μm. 所包裹的AgCl纳米粒子在纤维中呈规则排列. 沿着二氧化硅纤维生长方向,同一条二氧化硅纤维包裹多条氯化银纳米线.

A novel and simple method of synthesizing SiO2 nanofibers has been introduced. The SiO2 nanofibers prepared have well-defined structure, and its diameter is between 30~100 nm and the length more than 20 mm. AgCl nanoparticles showed regular arrangement in silica nanofibers. Many AgCl nanoparticles were arrayed one by one along the growth orientation of silica nanofiber as a thread, and every silica nanofiber was made up of many AgCl nanothreads.
