Will the performance of hydrophobic silicate sol change after long-term exposure in the natural environment?

Hydrophobic silicate sol is a colloidal material with special functions. It has been widely used in many fields due to its unique hydrophobic properties and chemical stability. However, whether its performance will change after long-term exposure in the natural environment is a common concern of users.
The hydrophobicity of hydrophobic silicate sol mainly comes from the chemical modification or physical treatment of its surface. This treatment makes the surface of the sol particles have a certain hydrophobicity, so that it can remain stable in the water environment. However, various factors in the natural environment, such as temperature, humidity, light, microorganisms, etc., may affect the performance of the sol.
In terms of temperature, high temperature may cause the destruction of the sol structure, thereby affecting its hydrophobic properties and chemical stability. Humidity changes may cause changes in the moisture on the surface of the sol particles, thereby affecting its overall performance. In addition, radiation such as ultraviolet rays in light may also have a destructive effect on the sol.
The role of microorganisms should not be ignored either. Microorganisms such as bacteria and fungi in the natural environment may attach to the surface of the sol and degrade or corrode the sol by secreting enzymes or acids, thereby affecting its performance.
However, hydrophobic silicate sol is not completely defenseless in the natural environment. Its internal silicate structure itself has a certain chemical stability and can resist certain acid-base corrosion and oxidation. In addition, the interaction between sol particles may also form a certain protective layer to further protect the sol from damage by the external environment.
In summary, the performance of hydrophobic silicate sol may indeed change after long-term exposure to the natural environment. However, the specific degree of change depends on many factors such as the preparation process of the sol, the use environment, and the exposure time. Therefore, when using hydrophobic silicate sol, it is necessary to fully consider its long-term stability and take corresponding protective measures to ensure that it can maintain stable performance during use.
