Effect of Doping Ratio on FTIR Spectrum of Coumarin Doped Polystyrene films

Mahasin F. Hadi Al-Kadhemy, Zahraa Sabaah Rasheed


Fourier transform infrared (FTIR) spectroscopy is one of the powerful tools for identifying and investigating the presence of various functional groups in polymers. We studied the transmission FTIR spectra of coumarin laser dye, polystyrene polymer, and coumarin doped polystyrene films with different doping ratio of coumarin solution. All samples prepared by casting method. Increasing doping ratio of coumarin solution will clear the role of coumarin laser dye on FTIR spectrum by appearing peaks refers to dye which have evaluated and compared with other researches..

KeyWord: FTIR Spectrum, Coumarin, Polystyrene Polymer, Effect of Doping Ratio, Dye Doped Polymer Films.
