Spectroscopic phase separation morphology

The final morphology of a network system depends greatly on the flow properties and phase separation of the reactive components as seen in Fig. 5)16-18,29] Naturally, design of appropriate processes requires the ability to directly investigate the progress of reaction. This includes monitoring the chemistry of cure with spectroscopic techniques such as FTIR, NMR,... 

To obtain the morphology information, including phase separation and crystalline, we can now use microscopic techniques, atomic force microscopy, transmission electron microscopy, electron tomography, variable-angle spectroscopic ellipsometry. X-ray photoemission spectroscopy, and grazing-incidence X-ray diffraction. The detailed information of this characterization methods can be found from the specific reference (Li et al., 2012 Huang et al., 2014).
