基于稳定化多孔硅及其复合含能材料制备与性能评价

Porous silica-based nanoenergy-containing materials have become a research hotspot in the field of energy-containing materials due to their unique energy-releasing properties, and electrochemical anodic oxidation technology has been widely used to prepare porous silica substrates, but its tendency to react with oxygen in air leads to a serious limitation on the practical application of the materials. In this paper, two stabilization treatment schemes, cathodic reduction method and anodic oxidation method, are used to observe and study using scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), fiber optic spectrometer and high-speed camera. The experiments show that: (1) after 5 months of air storage, the surface pore structure retention rate of the two stabilized treatments of porous silicon is enhanced by more than 40% compared with the untreated specimen; (2) FTIR analysis confirms that the stabilized treatments effectively inhibit the oxidation reaction, and the surface hydroxyl content is ranked as anodic oxidation<cathodic reduction<untreated; (3) after vacuum storage for one month, the cathodic reduction porous silica-based composite energy-containing materials exhibit (3) After 1 month of vacuum storage, the cathodically reduced porous silica-based composite energy-containing material showed the optimal explosive performance, and the stabilization effect was cathodically reduced > anodic oxidation > unstabilized.
