This paper presents the preparation of chitosan/nano‐TiO2films with different contents of nano‐TiO2by 3D printing technology. The ink solution for printing was prepared by dissolution of chitosan in 1 % acetic acid before dispersing nano‐TiO2in the chitosan solution by ultrasonic method. The investigated nano‐TiO2contents were of 3 and 5 wt.% in comparison with chitosan weight. The obtained chitosan/nano‐TiO2films were characterized by infrared spectroscopy (IR), field emission scanning electron microscopy (FESEM), and ultraviolet‐visible spectroscopy (UV‐Vis) methods. Besides, the water adsorption ability and moisture content in these films were also evaluated. The chitosan/nano‐TiO2films were used for adsorption of methylene blue in aqueous. The research results confirmed that the chitosan/nano‐TiO2films are promising adsorbents for removal of coloring matter.
