The concept of diffusion of light gases through polymers is a widely used in a variety of commercially available materials - food packaging materials, solar cell encapsulants, industrial separation membranes - with the entire field relying on the assumption that different polymers transport gases at different rates through them. The entire field rests upon the idea that diffusion of gases through polymers operate through a jump diffusion mechanism and by tuning the chemistry of the system, you can alter this and therefore alter the macroscopic diffusion coefficient. Our work aims to show that nanocomposites can solve problems faced by more traditional membranes (loss of function with time, brittleness .etc.) while simultaneously providing an experimental technique to probe the mechanism and measure microscopic diffusion parameters, thus providing a new framework for separation membranes.
