Facile Synthesis and Property Analysis of Silica/Phenanthroline Hybrid Composites

摘要: 为制备功能杂化材料，本文以纳米白炭黑(SiO₂)为原料，经氢氧化钠活化后，与邻菲啰啉在无水乙醇中加热回流制得白炭黑/邻菲啰啉杂化材料。采用扫描电镜、傅里叶变换红外光谱仪、X射线衍射仪和同步热分析仪对材料的形貌、结构、晶相及热稳定性进行表征，并研究其结构性能。结果表明，杂化材料晶型结构改变、结晶度提升，且耐高温性能优良，为其后续研究提供了实验依据。

Abstract: In order to fabricate functional hybrid materials, silica/phenanthroline hybrids were synthesized via a heating reflux method in anhydrous ethanol, using nano-silica (SiO₂) as the raw material after activation with sodium hydroxide. The morphology, structure, crystalline phase, and thermal stability of the prepared materials were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), and simultaneous thermal analysis (STA). Their structure-performance relationship was also investigated. The results indicate that the crystal structure of the hybrid materials was altered, their crystallinity was enhanced, and they exhibited excellent high-temperature resistance. This study provides an experimental basis for their subsequent research.
