Abstract The combinations of nano-ZnO with wood through simple and efficient physical methods to prepare environmentally friendly and versatile Nano-ZnO-coated Wood have important research and practical implications. In this paper, an environmentally friendly nano-ZnO-coated wood was prepared by physical magnetron sputtering using Pinus sylvestris L. var. mongholica Litv. The micro-characteristics, structure, wettability and colour change of the ZnO-coated wood were characterized and studied. For samples with a sputtering time of more than 3 min, the surface water contact angle exceeded 130° and had good hydrophobic properties. After a 168 h accelerated ultraviolet (UV) ageing test, the total colour difference (ΔE ∗) of the sample with a sputtering time of 75 min (200 °C) was 77% lower than that of the original wood. When the substrate was at 200 °C, the ZnO films deposited on the surface of the wood were evenly and densely arranged, forming almost a continuous film. It could be seen that the deposition of a nano-ZnO film on the surface of wood could significantly improve its hydrophobic properties and anti-UV photochromic properties.

环保型纳米氧化锌包覆木材的疏水和抗紫外线性能

摘要 通过简单有效的物理方法将纳米氧化锌与木材结合制备环保且用途广泛的纳米氧化锌包覆木材具有重要的研究和实际意义。在本文中，使用樟子松（Pinus sylvestris L. var.）通过物理磁控溅射制备了一种环保的纳米氧化锌涂层木材。mongholica Litv. 对ZnO涂层木材的微观特征、结构、润湿性和颜色变化进行了表征和研究。对于溅射时间超过 3 分钟的样品，表面水接触角超过 130°，具有良好的疏水性。经过 168 小时加速紫外线 (UV) 老化试验后，溅射时间为 75 分钟 (200 °C) 的样品的总色差 (ΔE *) 比原始木材低 77%。当基材在 200 ℃时，沉积在木材表面的 ZnO 薄膜均匀而致密地排列，几乎形成了连续的薄膜。可以看出，在木材表面沉积纳米ZnO薄膜可以显着提高其疏水性能和抗紫外线光致变色性能。
