Abstract
Natural based-cellulosic fibers are trending due to the global awareness regarding environmental health and because their properties make them a great alternative to the synthetic fibers. 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.
Highlights
Environmental concerns over global warming have encouraged academics to find new eco-friendly materials [1,2]
The effect of increasing the oxygen partial pressure on the surface morphology of TiO2 films deposited on glass substrates at P = 500 and 1000 W was investigated by using scanning electron microscopy (SEM)
Five samples of natural based-cellulosic fibers extracted from stems of the ginger lily plant (Hedychium gardnerianum) were investigated
Summary
Environmental concerns over global warming have encouraged academics to find new eco-friendly materials [1,2]. NBCF have numerous applications in almost all fields of engineering and have emerged as potentially reinforcement alternatives of advanced composite materials [3,4,5]. Stems of plants such as jute, flax, ramie, and hemp have been used to obtain NBCF [6]. Ginger lily grows in mild climates [8] and might even be harvested several times per year They are similar to all other NBCF in many aspects but reveal marked differences in the relative amounts of their main components (cellulose, lignin, and hemicellulose) [7,9]. Ginger lily fibers contain by weight ~6% hemicelluloses, ~12% lignin [7,9], and high cellulose content of ~79%, while cellulose content of sisal, jute, and hemp fibers has been found to be 65%, 61–71%, and 68%, respectively [7]
