Glassy Polymers—Diffusion, Sorption, Ageing and Applications

For the past few decades, researchers have been intrigued by glassy polymers, which applications ranging from gas separations to corrosion protection drug delivery systems. The techniques employed examine sorption and diffusion of small molecules in polymers are subject this review. Diffusion models regulated Fickian non-Fickian diffusion, with being more prevalent. characteristics determined isotherms, different proposed literature explain over last years. This review also includes polymers. Despite having many applications, current still difficulty implementing coating challenges due issues such as physical ageing, brittleness, etc., briefly discussed
