| Energy and environmental challenges caused by global development are attractive targets for membranes as population expands and emerging economies compete for resources. Conventional solution-processable polymers and inorganic materials each have limitations that currently prevent their use across the full spectrum of membrane-based separation applications. For polymers, penetrant size and shape-discriminating ability is often lower than desired. On the other hand, for pure inorganic membranes, brittleness and high manufacturing cost are drawbacks. Ideally, hybrid materials comprising blends of organic and inorganic materials can be formulated to combine the best characteristics of each of the components. Besides offering technical advantages, hybrids are compatible with existing economical processes for membrane formation. This compatibility is valuable, since maintaining attractive economics is crucial to compete successfully with other separation technologies. Some examples of these types of materials that offer the greatest promised will be discussed to illustrate the above issues, challenges and opportunities. |
