以聚硅乙炔为碳化硅前驱体, 用二氧化硅微球作为模板制备了反蛋白石结构的碳化硅光子晶体, 并对其耐热性进行了初步评价. 采用扫描电镜和透射电镜等方法对材料的多孔结构进行了表征, 利用X射线衍射对材料进行了物相分析, 并运用热重分析对材料的高温抗氧化性进行了初步表征. 结果表明, 制得的材料规整有序, 在空气气氛下900 ℃时残重为84%.

关键词: 聚硅乙炔, 反蛋白石, 多孔材料, 抗氧化

SiC inverse opal photonic crystal was prepared from infiltrating liquid polysilylacetylene into close-packed colloidal silica templates. The resultant sample was characterized by X-ray diffraction, transmission electron microscopy and scanning electron microscopy. The results showed that the material exhibited ordered porous structure, and the decomposition residue of the sample was 84% in air at 900 ℃.

Key words: polysilylacetylene, inverse opal, porous material, oxidative stability
