Abstract

Fourier transform infrared (FT-IR) spectroscopic imaging with focal plane array detectors has proved a powerful technique for rapid chemical visualization of samples, with a lateral resolution up to 10–15 μm in the transmission micro mode. In the present communication the application of this technique is described for the study of the diffusion of D2O into a polyamide 11 (PA11) film. Apart from the in situ visualization of the diffusion front propagation in the time-resolved FT-IR images, the type of diffusion and the diffusion coefficient of D2O in the investigated polyamide have been determined.
