Sampling Approaches in Fourier Transform Infrared Imaging Applied to Polymers

摘要

FTIR imaging is a powerful tool that combines enhanced visualisation with chemical information. However, prior to applying this method to polymer systems one needs to appreciate the advantages and limitations of a particular imaging mode, i.e. its spatial resolution and field of view. Therefore, there is a need to discuss the differences between the two main FTIR imaging modes: transmission and Attenuated Total Reflection (ATR) and to review recent developments in macro FTIR imaging that include innovative introduction of a diamond ATR accessory for imaging applications.
