MeSH headings : Diffusion; Electric Power Supplies; Kinetics; Models, Chemical; Organic Chemicals / chemistry; Polymers / chemistry; Sunlight; Thermodynamics
TL;DR: It is discovered that the diffusion of an NF-SMA into the donor polymer exhibits Arrhenius behaviour and that the activation energy Ea scales linearly with the enthalpic interaction parameters χH between the polymer and the NF- SMA, and the thermodynamically most unstable, hypo-miscible systems are the most kinetically stabilized.
