Diffusion Coefficients of Ferrocene in Composite Materials Containing Ambient Temperature Ionic Liquids

Diffusion coefficients ( D ) of ferrocene in materials composed of the ambient temperature ionic liquids 1,2‐dimethyl, 3‐(1‐propyl) imidazolium tetrafluoroborate or 1‐ethyl‐3‐methylimidazolium tetrafluoroborate and hexafluoropropylene‐vinylidene fluoride copolymer were estimated using chronoamperometry. The values of D obtained with the composite materials based on ranged from to and depended on the composition and pretreatment of the composite material. The latter value is equal to the diffusion coefficient of ferrocene in liquid . The values obtained with the composite materials based on ranged from to and they are lower by a factor of more than four than that of ferrocene in liquid .
