Fast-growing bamboo offers a sustainable alternative to meet the increasing demand for wood. However, its inherent hydrophilicity limits its performance, necessitating hydrophobic modifications to enhance longevity. In this study, 1 H,1 H,2 H,2 H- perfluorodecyltrimethoxysilane was used to anchor SiO nanoparticles onto bamboo surface, creating superhydrophobic coatings. The nanoparticles constructed a micro-/nano-rough structure on the bamboo surface, and fluorosilanes significantly reduced the surface energy of bamboo. The wettability, micro-morphology, chemical composition, and resistance to acid and alkali corrosion, mechanical abrasion, and UV aging of the superhydrophobic coatings were extensively investigated. The results demonstrated that the modified bamboo achieved a surface energy of 0.2±0.0 J/m and a water contact angle of 156.8±0.2°. Furthermore, the coating exhibited excellent chemical and physical stability. This straightforward and effective surface treatment method offers substantial potential for broadening bamboo's applications in outdoor environments.

液相沉积法在竹材上高效合成耐用超疏水SiO2@PFDMS涂层


快速生长的竹子提供了一种可持续的替代品，可以满足对木材日益增长的需求。然而，其固有的亲水性限制了其性能，需要进行疏水性修饰以延长使用寿命。在这项研究中，使用 1H,1H,2H,2H-全氟癸基三甲氧基硅烷将 SiO2 纳米颗粒锚定到竹子表面，形成超疏水涂层。纳米粒子在竹子表面构建了微/纳米粗糙结构，氟硅烷显着降低了竹子的表面能。对超疏水涂层的润湿性、微观形貌、化学成分以及耐酸碱腐蚀、机械磨损和紫外线老化进行了广泛的研究。结果表明，改性竹材的表面能达到0.2±0.0J/m，水接触角达到156.8±0.2°。此外，涂层表现出优异的化学和物理稳定性。这种简单有效的表面处理方法为扩大竹子在户外环境中的应用提供了巨大的潜力。
