Morphology Observation Technology
Surface/Interface Morphology Observation
Various microscopes and surface profilers are used to observe the morphology of polarizing film.
Morphological observation is an important element in not only the external inspection of polarizing films,where exterior appearance is considered to be extremely important, but also in product design and defect analysis. Various types of microscope (scanning electron microscopes (SEM), transmission electron microscopes (TEM), scanning probe microscopes (SPM)), laser microanalysis (LM) and profilometers are used in form observation, meaning that it is possible to observe samples ranging in size from tens of centimeters to as small as several nanometers. Consideration is also given to preprocessing methods, which can contribute to more effective observation.

Structural Analysis of Polymer Separation Membranes
Using scanning electron microscopy and other surface analysis techniques to contribute to new product development and investigation of contamination sources
The polymer separation membranes used in water treatment are subjected to multiple analyses to assist with new product development. Techniques used include scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), Fourier transform infrared spectroscopy (FT-IR), and a range of surface analysis techniques such as scanning probe microscopy (SPM) and membrane surface potentiometry. These evaluation technologies can also be applied to investigate pollution sources and can be of assistance in troubleshooting and similar tasks.
