The sample cannot be dissolved, so the test need to be performed on a solid state.
Hi Mehdi, I think you can run the analysis of your sample using UV-Vis spectrophotometer (with sample compartment/holder for solid) or Diffused Reflectance Spectroscopy (DRS). Due to sample preparation for testing, you can follow the program instruction of the instrument such as wavenumber range, mode (X and Y), scan control and others.
Hi Mehdi, i suggest you to run a FTIR analysis for your sample, it is a more interesting result.
Use UV-Vis. spectrophotometer to test your solid smaple as suggested by Rudy S.
No need to dissolve
I suggest you to make a FTIR analysis for your sample. and for UV-Vis, if your sample is transparent, you can make it lamelliform for this test , but if not transparent, only the results of reflectivity can be obtained.
For preparation of nanocomposite in solid state you can use extruder/internal mixer along with nanoparticles and cast on mold. Alternatively, You can introduce any salt while preparing the film and later reduce chemically or by using radiation. You must do XRD for characterization. For UV-VIS your film needs to be transparent. If possible use one film without nanoparticle as reference.
Use UV-VIS spectra. It is very easy. you can do it in solid state without dissolving in liquid. Here as a blank, please use air. Use air always as blank and your nanocomposite as sample.
It would be great, if you would use UV-DRS (Differential Reflectance spectroscopy) for solid, powder like samples. The test for your samples can be done directly, with this instrument. Since this spectroscopy is preferred over, for the ease of convenience and its ability to eliminate instrumental variations, any undesirable effect of oxides etc.
