Abstract
In this study, ramie fiber was employed to prepare cellulose triacetate (CTA) films. Subsequently, the photodegradation behaviors without photosensitizers of CTA films were carried out in photodegradation chambers at 40 °C. Additionally, the photodegradation procedure of films was assessed by the attenuated total reflection infrared (ATR-IR), 1H nuclear magnetic resonance (1H NMR), scanning electron microscope (SEM), thermal properties, degree of substitution (DS), and tensile strength. The research consequences indicated that the mechanical strength of the CTA films was decreased significantly after ultraviolet (UV) irradiation for 300 h. However, the DS of the films is almost invariable when they are exposed to UV irradiation. Meanwhile, the suggested mechanism for photodegradation of CTA was also exhibited in this paper. This study provides a mild and potential pre-treatment approach for the biodegradation of LCD used waste CTA films.
