The effect of temperature (103 K < T < 303 K) upon the limiting fluorescence anisotropy r0 of POPOP was investigated in a cellulose acetate film. A slow increase in r0 was observed when reducing the temperature. Based on the Jabłoński theory, the frequency of the torsional vibrations of POPOP was determined to be w = 1.3 x 1012s−1. The depolarization due to these torsional vibrations was found to occur immediately following excitation during the thermal relaxation of the luminescent centre, thus somewhat lowering the value of the fundamental fluorescence anisotropy rf to the limiting r0 value.

This paper reports a novel process of nanofiber formation in regenerated cellulose from cellulose acetate (CA) film by saponification and stretching. Saponification of CA film was performed using sodium methoxide in methanol solution. Regeneration of cellulose during the saponification of CA was verified by taking Fourier transformation infrared spectrum. Cross-sectional images of the saponified and stretched CA film revealed an aligned nanofiber structure. The Young’s modulus and ultimate strength were enhanced approximately 630% and 450%, respectively, which might be due to the formation of multiple hydrogen bonds after sodium methoxide treatment along with the nanofiber formation. Since the saponified CA films are transparent, biodegradable, and possess high mechanical strength, they can be used as a biomaterial.
