Wood is an irreplaceable structural and biodegradable material, which is subject to swelling, shrinkage, significant deformation of structural elements, and products when its moisture content changes. This paper proposes wood surface modification with reactive copolymers based on glycidyl methacrylate and alkyl methacrylates to impart superhydrophobic properties with initial contact angles up to 166°. Scanning electron microscopy and energy dispersive X-ray spectroscopy were used to study the features of polymer coating formation and to determine the modifier penetration depth, which was more than 1000 μm. It has been shown that copolymers do not fill the initial capillary system of wood. Modified wood is characterized by stable water-repellent properties with low-water diffusion rates, with the water absorption rate reduced by more than three times compared to that of initial wood. Polymer coatings provide water repellency, retain the appearance of original wood, and provide increased buoyancy.

用基于甲基丙烯酸缩水甘油酯和甲基丙烯酸烷基酯的共聚物改性木材以赋予超疏水性能

木材是不可替代的结构和可生物降解材料，当其含水量发生变化时，会发生膨胀、收缩、结构元件和产品的显着变形。本文提出用基于甲基丙烯酸缩水甘油酯和甲基丙烯酸烷基酯的反应性共聚物对木材表面进行改性，以赋予初始接触角高达 166° 的超疏水特性。使用扫描电子显微镜和能量色散 X 射线光谱仪研究聚合物涂层形成的特征并确定改性剂渗透深度超过 1000 μm。已经表明共聚物不会填充木材的初始毛细管系统。改性木材的特点是具有稳定的防水性能和低水扩散率，吸水率比初始木材降低三倍以上。聚合物涂层提供防水性，保留原始木材的外观，并提供更高的浮力。
