Formatted abstract
The current study investigates the diffusion of Bisphenol]F, TGDDM and Triglycidyl]PAminophenol type epoxies into polyvinylidene fluoride (PVDF), polyethersulfone (PES) and polyetherimide (PEI) films using fourier transform infrared spectroscopy (FTIR) and gravimetric analysis. The epoxies were used without a curing agent to determine if there is a link between diffusivity and individual epoxy components.

It was found that the diffusivity of the epoxy components was dependant on the molecular size of the epoxies as well as the state of the thermoplastics (o.e. amorphous or semicrystalline). An amorphous material was more likely to diffuse into the epoxy while the semicrystalline material was more likely to retain its shape while allowing for diffusion from the epoxy to the thermoplastic film.
