Due to the hydrophilic nature of paper mulch, it is easy to absorb water during use, which will reduce its mechanical properties and durability, thus affecting its performance. Therefore, the development of paper mulch is hindered. In this paper, in order to improve the hydrophobic performance of paper mulch, we successfully prepared superhydrophobic silicon dioxide/paper mulch by simple, efficient and environmentally friendly solution immersion method without the introduction of adhesive. The contact Angle and rolling Angle between the prepared super hydrophobic paper mulch and water are 156.4° and 1.8°, respectively. The water drop is easy to roll on its surface, and has excellent water drop bouncing performance, which can play an excellent water-repellent function. Studies have shown that the superhydrophobicity of silicon dioxide/paper mulch is less affected by its surface roughness, mainly because the surface covered by a layer of silicon dioxide reduces the surface energy of the paper mulch, and the silicon dioxide on the surface of the paper mulch is enough to reduce the damage of aging on the paper mulch. In addition, the decrease in the contact angle of the SiO₂/paper mulch and the increase in the rolling angle after aging are due to the decrease in the amount of SiO₂ adhesion on the surface of the paper mulch and the increase in the degree of exposure of fiber bundles. Studies have found that the superhydrophobic paper mulch can reduce the influence of its own aging on its rolling angle after being subjected to friction.

由于纸地膜的亲水性，在使用过程中容易吸水，会降低其机械性能和耐久性，从而影响其性能。因此，阻碍了纸覆盖物的发展。在本文中，为了提高纸膜的疏水性能，我们在不引入粘合剂的情况下，通过简单、高效、环保的溶液浸泡法成功制备了超疏水二氧化硅/纸膜。制备的超疏水纸膜与水的接触角和滚动角分别为156.4°和1.8°。水滴在其表面易于滚动，具有优良的水滴弹跳性能，可发挥优良的防水功能。研究表明，二氧化硅/纸地膜的超疏水性受其表面粗糙度的影响较小，主要是因为表面覆盖一层二氧化硅降低了纸地膜的表面能，而纸表面的二氧化硅覆盖物足以减少老化对纸覆盖物的损害。此外，SiO 的接触角减小₂ /纸地膜和老化后滚动角的增加是由于纸地膜表面SiO ₂粘附量减少和纤维束暴露程度增加所致。研究发现，超疏水纸膜在受到摩擦后，可以减少其自身老化对其滚动角的影响。
