I have made a nanocomposite, by adding two chemical compounds and I want to check there are some chemical bonded internally or not..so which area I should concern more?
Hello Mr. Kannangara.
You can try with FTIR. Do an FTIR analysis of separate phases and the composite. If an new bond is formed it should be visible in the spectrum by comparing the spectrum of the composite to that of separate phases.
Good luck
Peak positions in XPS are sensitive to the oxidation or hybridization states of elements. The information is used to validate whether primary chemical bonds form between elements. This is especially useful to determine different types of covalent or ionic bonds. XPS works across all groups of materials (metals, ceramics, semiconductors, polymers).
The presence of peaks and their positions in FTIR indicate the formation of bonds and the force constant of the bond. FTIR works best in polymers and otherwise is unusable or too complicated for other materials (metals, ceramics, and semiconductors).
Other methods that may be useful to determine chemical bonding state include the XAFS and its related set of spectroscopies.
