Raman and FTIR Analysis of Polymer Composite Films Deposited With IR Co2 Laser
Production of electrically conductive thin polymer composite films, sensitive to toxic gases, were achieved by deposition with pulsed IR CO2 laser. Laser ablation was performed by varying the energy density and focus of the incident beam, deposition atmosphere and number of pulses. Towards optimizing the parameters for the laser ablation we obtained conductive polymer composite films and carbon nanostructures. The properties of the deposited composite films were evaluated by FTIR and Raman spectroscopy. The goal was to optimize the laser system parameters in favor of obtaining stoichiometry transfer between target and substrate and depositing films with no significant defects in the structure, and successful production of electrically conductive composite films.
