A novel two-step process was developed to synthesize and deposit SiO2/TiO2 multilayer films onto the cotton fibers. In the first step. SiO2 particles on cotton fiber surface were synthesized via tetraethoxysilane hydrolysis in the presence of cotton fibers, in order to protect the fibers against photo-catalytic decomposition by TiO2 nanoparticles. In the second step, the growth of TiO2 nanoparticles into the modified cotton fiber surface was carried out via a sol-gel method at the temperature as low as 100 degrees C. The as-obtained SiO2/TiO2 multilayer films coated on cotton fibers were characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, atomic force microscopy and X-ray diffraction, respectively.
