Tannic-Acid-Cross-Linked and TiO<sub>2</sub>-Nanoparticle-Reinforced Chitosan-Based Nanocomposite Film

Tannic-Acid-Cross-Linked and TiO<sub>2</sub>-Nanoparticle-Reinforced Chitosan-Based Nanocomposite Film

A chitosan-based nanocomposite film with tannic acid (TA) as a cross-linker and titanium dioxide nanoparticles (TiO<sub>2</sub>) as a reinforcing agent was developed with a solution casting technique. TA and TiO<sub>2</sub> are biocompatible with chitosan, and this paper stud...
