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