Popis: Hydrophobic paper with a static water contact angle (WCA) equal to 140° ± 0.2° has been synthesized by functionalization of the cellulose fibers (CF) with palmitic acid (PA) through layered double zinc and aluminium hydroxides interface (PA-Zn/Al LDH-CF). Different techniques, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscope (SEM) were used to confirm the grafting of palmitic acid on the cellulose surface. The hydrophobic nature of the PA-Zn/Al LDH-CF was due to the grafting of palmitic acid on the metal hydroxide surfaces which was confirmed by measuring the WCA of the PA-Zn/Al LDH-CF samples. The results showed that using PA-Zn/Al LDH-CF paper can improve the hydrophobic property of cellulose as a renewable material in packaging coatings industry.
