Wetting is a key problem in wood finishing because water causes deterioration and reduces the durability of wood. Herein, hydrophilic wood has been modified into a hydrophobic wood through simple surface coating using polyvinyl acetate (PVAc) / reduced graphene oxide (rGO)-poly (diallyl dimethylammonium chloride) (PDDA). The synthesized graphene oxide (GO) from graphene flakes is used for chemical modification with urotropin in presence of sodium borohydride. The hydrophobic property of PVAc has been increased by modified graphene oxide dispersed at the presence of PDDA in methanol. The synthesized polymer composite is used coating on the various wood surfaces (radial and cross-sectional). Synthesized materials are characterized by extensive characterization techniques. The water contact angle of wood surface coated with PVAc/rGO-PDDA shows 187.8 % better than uncoated wood and 20.7 % better than PVAc coated wood and 2.4 % better than commercial wood stain coated wood. This facile, low cost and eco-friendly approach could be used in a variety of applications.

润湿是木材涂饰中的关键问题，因为水会导致变质并降低木材的耐久性。在本文中，已经通过使用聚乙酸乙烯酯（PVAc）/还原的氧化石墨烯（rGO）-聚（二烯丙基二甲基氯化铵）（PDDA）的简单表面涂覆将亲水性木材改性为疏水性木材。由石墨烯薄片合成的氧化石墨烯（GO）用于在硼氢化钠存在下用urotropin进行化学修饰。通过在PDDA存在下分散在甲醇中的改性氧化石墨烯，可以提高PVAc的疏水性。合成的聚合物复合材料用于涂覆在各种木材表面（径向和横截面）上。合成材料的特征在于广泛的表征技术。涂有PVAc / rGO-PDDA的木材表面的水接触角显示为187。比未涂层的木材好8％，比PVAc涂层的木材好20.7％，比商品木纹涂层的木材好2.4％。这种简便，低成本和环保的方法可用于多种应用。
