The research on surface morphology and pore structure regulation of precipitated silica is an important field involving the adjustment of silica particle morphology and pore structure. These control studies can be achieved by changing the preparation conditions of silica, adding surface modifiers or through subsequent treatment. The following are several key research directions:

Surface morphology control: Study how to adjust the surface morphology of precipitated silica by controlling the synthesis conditions. Different parameters such as synthesis temperature, precipitation rate, and solvent selection can affect the morphology of silica particles, such as spherical, fibrous, and flake. Regulating the surface morphology can affect the dispersibility, thickening effect, strengthening effect and other properties of silica.

Surface modification: By using different surface modifiers, such as silane coupling agents, polymers, etc., the surface properties of precipitated silica can be changed. Surface modification can enhance the compatibility of silica with the polymer matrix, optimize the performance of composites, and improve the dispersion stability of silica.

Pore structure adjustment: The pore structure of precipitated silica is an important factor affecting its performance. By controlling the synthesis conditions and subsequent treatment methods of silica, the pore size, distribution and shape of silica can be adjusted. Optimizing the pore structure can improve the adsorption performance and energy storage performance of silica.

Surface and pore structure characterization: Detailed surface and pore structure characterization is fundamental for regulatory studies. Commonly used characterization methods include scanning electron microscopy (SEM), transmission electron microscopy (TEM), specific surface area measurement (such as BET surface area measurement), pore size distribution measurement, etc.

Theoretical simulation and calculation: With the help of theoretical simulation and calculation methods, the influence of surface morphology and pore structure on the performance of precipitated silica is studied. This can deepen the understanding of silica microstructure-property relationship and provide guidance for further optimized design.

Through these studies on the regulation of surface morphology and pore structure, the directional optimization of the performance of precipitated silica can be realized, and its application in the fields of paint thickener, rubber reinforcing agent, catalyst carrier, environmental adsorbent, energy storage material, etc. Provide more possibilities. This also helps to promote the further development and application of silica in the preparation of nanomaterials and other applications
