Uv shielding properties of cellulose/tio 2 composite film

Abstract

Cellulose/TiO 2 composite film was prepared for UV shielding applications. Cellulose was extracted from sugarcane bagasse by ball milling process. The cellulose/ TiO 2 composite film with different concentrations of cellulose showed a synergic feature of optical transparency and UV-blocking. The crystalline structure of cellulose was characterized by X-ray diffraction (XRD). The treated cellulose has higher crystallinity than the untreated cellulose. Fourier transform infrared spectroscopy ( FT-IR) analysis shows the evidence of chemical treatment hemicellulose and lignin removal from sugarcane bagasse. The optical properties were measured by UV-Vis spectrometer, the results of TiO 2 and cellulose solution correspond to UV-A and UV-C absorbance regions with high transparent of cellulose composite films. The revealed results are essential for UV protecting materials application.
