Lecture will discuss various methods for modifying membranes for given separation purposes, focusing mostly on membranes for gas separation and liquid separation by membrane distillation and pervaporation. Moreover, the modification of ceramic membranes for the immobilization of enzyme (Candida antarctica lipase B) will be discussed.
The goal of this optimization is to improve the affinity between membrane and separating systems. By merging material and membrane science, materials with adjusted morphology and controlled separation features can be prepared. The modification can be related to the adjustment of the surface nano-architecture and/or bulk membrane structure. Polymeric membranes with commercial and synthesized nanofillers will be described in detail. The surface modification of ceramic materials will be discussed. Eventually, several practical applications of the pristine and modified membranes in gas separation, pervaporation and membrane distillation will be presented. Finally, the efficiency of the enzyme immobilization will be also shown.
