文摘
- •
Silicalite-1 was successfully modified with various alkoxysilanes.
- •
Effect of different alkoxysilanes on the performance of the MMMs was compared.
- •
After modification, the mixed matrix membranes showed better selectivity to ethanol.
- •
A novel mathematical model for evaluating the performance of the MMMs was proposed.
