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.

静态水接触角（WCA）等于140°±0.2°的疏水性纸是通过将纤维素纤维（CF）与棕榈酸（PA）通过层状双锌和氢氧化铝的界面（PA-Zn / Al）官能化而合成的LDH-CF）。使用不同的技术，X射线衍射（XRD），傅里叶变换红外光谱（FTIR）和扫描电子显微镜（SEM）确认棕榈酸在纤维素表面的接枝。PA-Zn / Al LDH-CF的疏水性是由于棕榈酸在金属氢氧化物表面上的接枝，这是通过测量PA-Zn / Al LDH-CF样品的WCA证实的。结果表明，在包装涂料行业中，使用PA-Zn / Al LDH-CF纸可以改善纤维素作为可再生材料的疏水性。
