Effect of Temperature and Concentration on the Optical Properties of PVC Solutions
In this paper, effects of temperature and concentration on theabsorption spectra for Polyvinyl chloride solutions are studied at wavelengthsfrom 200 to 400 nm and with the range of temperature 20, 30, 40, 50, and 60degrees (Co). Electronic absorption spectra were examined over thewavelength range 20...

| description | In this paper, effects of temperature and concentration on theabsorption spectra for Polyvinyl chloride solutions are studied at wavelengthsfrom 200 to 400 nm and with the range of temperature 20, 30, 40, 50, and 60degrees (Co). Electronic absorption spectra were examined over thewavelength range 200-400 nm by different concentrations (1x10-3, 8x10-4,6.5x10-4, 5x10-4 and 3x10-4)[M]. The UV spectra shifted slightly towardslarge wavelength with increasing the temperature. The values of the energygap of polyvinyl chloride are decreasing as concentration and temperatureincreased. The data shows that the refractive index of the polymer decreaseswith increasing the wavelength and temperature. The relationship between theabsorption coefficient and photon energy of the PVC solutions are calculated. |
