Abstract

In this review, we discussed fabrication methods, applications and recent trends of polybenzimidazole membranes which have the highest thermal resistance among the commercial polymers in existence. First of all, basic and modified with specific purpose synthesis method of polybenzimidazole and its own unique features including a mechanical and chemical properties are summarized. Furthermore, various polybenzimidazole membranes are classified by types and methods and, using their excellent properties, various applications and possible field to take advantage of the potential are also summarized. Next, we discussed about not only advantages of polybenzimidazole membranes but also directions of state-of-the-art trends. Lastly, the limit of polybenzimidazole membranes and its complements are also analyzed.
