Electrochemical Processes in Polymers of Intrinsic Microporosity

Polymers of intrinsic microporosity (or PIMs) have been developed over the past decade as molecularly rigid and highly processable materials that are readily applied to electrode surfaces or employed as free-standing membranes. Two prototypical PIMs are PIM-1 [1] and PIM-EA-TB [2]. Both possess rigid molecular backbones and pack into porous solid/glassy films with high surface area and with typically 1 nm pore size [3].

PIMs have been introduced into electrochemical applications in energy storage devices [3] and in sensors [4]. They provide fertile ground for fundamental studies on ion transport and electroosmotic water transport [5]. Intrinsic microporosity leads to binding and transport with size selectivity and chemical selectivity. Binding of gases into nanoparticulate PIM materials is responsible for gas activity changes under triphasic conditions [6] and could be beneficial in electroanalytical processes based for example on gaseous oxygen and hydrogen.
