==Description==

*The course is designed by American University to experiment different aspects of PVOH films.

*During the course PVOH films with different molecular weight will be produced. Effects of cross-linking, addition of different molecules such as gluteraldehyde, different acids, porphrin will be also tested.

*UV-Vis spectrum, Atomic Absorption spectrum, X-Ray, FTIR, DMA, ISE and many other instruments will be used to analyze the results.
