Papers with nanoscaled surface roughness and hydrophobically modification have been widely used in daily life. However, the relatively complex preparation process, high costs and harmful compounds have largely limited their applications. This research aims to fabricate superhydrophobic papers with low cost and nontoxic materials. The surface of cellulose fibers was initially coated with a film of SiO nanoparticles via sol-gel process. After papermaking and subsequent modification with hexadecyltrimethoxysilane through a simple solution-immersion process, the paper showed excellent superhydrophobic properties, with water contact angles (WCA) larger than 150°. Moreover, the prepared paper also showed superior mechanical durability against 10 times of deformation. The whole preparation process was carried out in a mild environment, with no intricate instruments or toxic chemicals, which has the potential of large-scale industrial production and application.
具有纳米级表面粗糙度和疏水改性的纸张已在日常生活中广泛使用。然而，相对复杂的制备过程、高成本和有害化合物在很大程度上限制了它们的应用。本研究旨在用低成本和无毒材料制备超疏水纸张。纤维素纤维表面首先通过溶胶 - 凝胶法涂覆一层SiO纳米颗粒薄膜。经过造纸并通过简单的溶液浸渍法用十六烷基三甲氧基硅烷进行后续改性后，纸张表现出优异的超疏水性能，水接触角（WCA）大于150°。此外，制备的纸张在经受10次变形时还表现出优异的机械耐久性。整个制备过程在温和的环境中进行，无需复杂的仪器或有毒化学品，具有大规模工业生产和应用的潜力。
