Review Questions
How does hydrothermal synthesis influence the properties of inorganic membranes?
Hydrothermal synthesis directly influences the properties of inorganic membranes by controlling factors such as crystallinity, pore size, and morphology during the production process. By adjusting temperature and pressure conditions, different crystalline structures can be formed, which impacts the membrane's filtration capabilities. This method allows for fine-tuning of material characteristics that enhance the membrane's selectivity and permeability.
Discuss how hydrothermal synthesis can be adapted to create composite membranes and what benefits this provides.
Hydrothermal synthesis can be adapted to create composite membranes by incorporating various materials into the synthesis process. This allows for the integration of functionalities from different materials, leading to improved performance in specific applications such as water treatment. The resulting composite membranes often exhibit enhanced mechanical strength, chemical stability, and selective permeability compared to their inorganic counterparts alone.
