More Information
Summary:Epoxy resin (DGEBA/TETA) is commonly used as an adhesive material. When this material is subjected to low temperatures for an extended period of time, it undergoes changes in inter/intramolecular vibrations which has been probed in this research through a combination of terahertz spectroscopy, differential scanning calorimetry and infrared spectroscopy. Distinctive morphological changes of the virgin material are observed for the exposed material at cold temperature which can be attributed to incomplete reversibility of segmental as well as entire molecular chain mobility.
