Description
The Brill transition is a phase transition process in polyamides, that has been related with structural changes between the hydrogen bonds of the lateral functional groups (C=O) and (N-H). In this study we show the potential of Raman spectroscopy for exploring this phase transition in polyamide PA66 (nylon 6,6). Raman spectra were collected during a step by step heating and cooling process of the sample from 30°C to 240°C, allowing to grasp signatures of the Brill transition from peak parameters of specific vibrational modes, and to verify the Brill transition temperature as well as the reversibility of this phase transition.
