| 摘要: |
| 采用简单易行的化学镀方法，在较低的温度下制备出一种新型的玄武岩纤维／镍核壳结构。SEM、XRD、XPS分析结果表明，金属Ni颗粒吸附在玄武岩纤维表面，形成了一层均匀连续的镍壳层。通过对试验结果进行分析，得出了制备玄武岩纤维／镍核壳结构的最佳温度和pH值分别为50℃和10．0。文中对化学镀核壳结构的形成机理也进行了初步分析。 |

| Abstract: |
| Basalt fibers/nickel core-shell structures were synthesized by an electroless plating method at low temperature. The core-shell structures were characterized by means of SEM and their components were analyzed by EDS, XRD and XPS. The results showed that the surface of basalt fibers was coated by a continuous and uniform nickel shells. Especially, the optimal temperature and pH value of electroless plating, namely, 50℃ and 10.0, have been ascertained. The possible mechanism of the formation of basalt fibers/nickel core-shell structures was discussed. |
