However, these fibers also have some hindrances that can be solved with their functionalization. The present study concerns modification of the surface of natural based-cellulosic fibers extracted from stems of the ginger lily plant (Hedychium gardnerianum) with TiO2 films deposited by DC magnetron sputtering using a titanium (Ti) target. A detailed characterization of the TiO2-coated fibers was investigated by Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The results revealed that the sputtered TiO2 films can be attached to the ginger lily fibers mainly by their OH groups. XPS analysis further shows that C-OH group is not dominant, which means that no pure cellulose is present at the surface.2974597engCellulose fibersFiber functionalizationFourier transform infrared spectroscopy (FTIR)Hedychium gardnerianumTiO filmsX-ray photoelectron spectroscopy (XPS)Surfaces and InterfacesSurfaces, Coatings and FilmsMaterials Chemistryjournal article10.3390/coatings10030287https://www.scopus.com/pages/publications/85083049316
