Abstract :
The effect of IR laser pulses fluencies on the dielectric properties, X-ray diffraction, and Fourier Transform Infrared spectroscopy (FTIR), for Makrofol-DE 1-1 CC polycarbonate has been investigated in the temperature and frequency ranges of 300-375K and 10kHz-4MHz, respectively. IR laser fluencies are set from 0.47 to 7.07 J/cm2. Three relaxation processes namely, a, p, and y have been obtained. X-ray diffraction and FTIR spectroscopy have revealed that, the irradiation of Makrofol at the fluence range 0.94-7.07 J/cm2 causes crosslinking formation inside the sample. The attained results suggested strongly the applicability of Makrofol-DE in IR laser pulses sensors.
