In this paper, we aim to evaluate chemically and optically, three types of hydrogels. Thus, the phase transitions that take place during the water-polymer interaction, present in hydrogels by thermal analysis techniques, namely differential dynamic calorimetry (DSC) will be studied. These studies will be correlated with experimental results obtained by optical methods (spectroscopy in the field of THz) and will lead to a better understanding of the specific properties of hydrogels for medical applications. In this collaboration on the study of hydrogels by optical and chemical methods, we aim to deepen research in the field of development of new hydrogels with medical applications, obtained by processing with ionizing radiation and understanding the structure-properties relationship of these materials. We thus determined the different types of phase transitions of the water absorbed in a polymeric material; the experimental data obtained will lead to the understanding of the structural properties that define a material in the form of a hydrogel; it will be possible to evaluate the interaction mechanisms of water-polymer-active principles with a role in the accelerated healing of some skin wounds. From an optical and spectroscopic point of view, hydrogels were studied in the THz domain, by obtaining transmission spectra and refractive indices, in the 0.1-3THz frequency range, using the THz-TDS spectroscopic kit (THz-time domain spectroscopy).
