摘　　要：在加热条件下采用氢化硅烷化反应对多孔硅表面进行改性,通过扫描电子显微镜、红外光谱及元素分析等手段表征了多孔硅改性前后的结构和组成,研究了不同反应时间对其性能的影响.结果表明,反应3 h后制得了超疏水表面的多孔硅,其在碱性及空气环境中具有良好的稳定性.The porous silicon has been widely used in many fields due to its great optical properties,but the silicon hydride bonds(Si-H)on the surface of porous silicon were sensitive to the water and oxygen,which will affect the performance of porous silicon.Therefore,it was critically necessary to improve the porous silicon stability by the surface modification.In this article,the surface modification of porous silicon was processed by the hydrosilylation method under the heating conditions.The structure and composition of the functionality porous silicon were characterized and tested by Fourier transform infrared spectroscopy,energy dispersive spectrometer,scanning electron microscopy.The effect of different reaction time on grafting porous silicon was investigated.The results show that the superhydrophobic porous silicon was prepared after 3 h reaction,and it exhibited great stability in the alkaline and air environment.
