Dear Maryam,

According to the type of polymer, you can find the main peaks that show the main functional group of polymer. If polymerization reaction was completely done, the main peak must be appeared, otherwise, some of main functional group wont appear in FTIR analysis.

Is it possible to identify the type polymer?

If I know the type of polymer, I can send you a reference to find the main peak.

Dear all, all chemical groups (functional or not) their absorption bands are tabulated according to their modes of vibrations. However, since you are dealing with a composite material you will be lucky to get detailled structural information, shielding effect is really pronounced. Other modes of IR spectroscopie such as Raman and ATR are more powerfull in unvestigating hybrid materials. My Regards

You should obtain at least four spectra: 1) spectrum of pure reinforcement such as fiber or filler using Kir pellet method, 2) spectrum of pure unpolymerized resin using KBr plate method, 3) spectrum of polymerized resin on KBr plate, and finally 4) the spectrum of the composite ground and made into KBr pellet. The spectrum 1) and 3) will help you interpret the composite spectrum identifying each peak to the reinforcement and polymerized resin. I doubt that if you will see unique peak that are not either in the reinforcement or polymerized resin unless the reinforcing material is a nano filler. You can Google the spectrum of those pure materials to find band assignment. Chances are that you will be able to find the paper reporting the band assignment for the material, unless you are working on the material you synthesized and is the world supply.
