Difference Between Fickian and Non Fickian Diffusion
Main Difference – Fickian vs Non Fickian Diffusion Diffusion is the movement of molecules from a region of high concentration to a region of low concentration. In other words, the molecules move through a concentration gradient. Therefore, the factors that affect the concentration gradient will also affect the diffusion. However, the diffusion that takes place in solid substances such as polymers is very different from that of liquids and gases.
