Abstract

Cellulose/TiO2 composite film was prepared for UV shielding applications. Cellulose was extracted from sugarcane bagasse by ball milling process. The cellulose/ TiO2 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 ( FTIR) 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 TiO2 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.
