The performance of a composite membrane is influenced by the thickness and structure of its support layer, in this case polypropylene (PP). Here, I will outline some of the effects of thickness and structure on the filtration performance of composite membranes:
Effect of thickness of PP support film on composite film
Influence of the structure of PP film as support layer on the composite film
From the above analysis, it can be seen that the thickness and structure of the PP support layer will affect the mechanical strength, permeability and filtration efficiency of the composite membrane. A balance between these factors is critical to optimize membrane performance. Further optimization can be achieved by considering specific application and operating conditions such as the type of contaminants, feed composition and desired flux rate, while we need to look at the properties of the PP support layer such as its thickness, pore size and surface area ;Find a balance between pore size and permeability to achieve ideal filtering effect. Different PP support layers can be thoroughly tested and analyzed to determine the best combination of thickness, pore size and surface area. This can be done through experiments and simulations and gathering feedback from customers and stakeholders.
