| Abstract
| - In the present work, dynamic water sorption processes in a series of poly(ether imide) (PEI) modified diglycidylether bisphenol A/(4,4‘-diaminodiphenyl)sulfone (DGEBA/DDS) systems were investigated. The clear pictureof the existing state and the diffusion process of water molecules in the blends was first elucidated by two-dimensional (2D) correlation analysis (based on attenuated total reflection Fourier transfer infrared (ATR-FTIR) measurement), and the novel technique used here could be the most effective as well as convenientway to perform the dynamic analysis on such investigations. Furthermore, by means of scanning electronmicroscopy (SEM), the delicate relationship between dynamic water sorption behavior and the morphologyresulting from phase separation was also discussed. Two states of water as free/bound water were found inthe systems, the diffusion sequence of which suggested not only composite-dependence but also morphology-dependence.
