Study on Preparation of Elastic Silica Aerogel Based on SEM Analysis

In order to explore and study the preparation of elastic silica aerogel, it is studied and discussed on the basis of SEM. The overall effect, comprehensive performance, and coupling degree of the preparation of silica gel are compared and analyzed by conventional analysis method and SEM analysis method, and it can be clearly seen that the SEM analysis method is better than the previous conventional analysis method. The scanning speed, working distance, imaging resolution, and result accuracy of the SEM analysis method are higher. At the same time, the SEM analysis method is simpler than the ideal process. According to the special properties of the material itself, the nanoporous materials are with high porosity, high specific surface area, low density, and low thermal conductivity; and the porous three-dimensional spatial network structure, in optics, electricity is widely used in thermal insulation, environmental protection, catalysis, chemical industry, and other fields. Based on SEM, the instrument has high resolution, deep image field, three-dimensional sense, simple sample preparation, and comprehensive analysis; the silica aerogel has a spatial network structure, with an aperture range of 10~50 nm; compared with ordinary silica aerogel gel, the preparation of elastic silica aerogel can withstand higher temperature based on SEM analysis; stable quality and elasticity expand the application range of aerogel gel, making it more widely used in shock absorption, heat insulation, sound insulation, and other fields, effectively achieving the goal of energy conservation and emission reduction.
