Abstract Wood veneer had been widely used in interior decoration or fitment, but its application was still limited due to deformation after absorbing water and bacterial erosion. In this paper, a Cu coating owned superhydrophobic and antibacterial capabilities on wood veneer was fabricated by a facile and valid method. The wood veneer with superhydrophobic and antibacterial properties was prepared by self-polymerization of dopamine, chemical deposition of Cu nanoparticles, and hydrophobic modification using fluorosilane. The water contact angle and sliding angle of obtained Cu coating reached 155.7° and 4°, respectively. Meanwhile, the as-prepared coating showed resistance to acid or base solutions with different pH values, different temperatures aging and mechanical damages, and also displayed a good self-cleaning ability. In addition, the modified wood exhibited outstanding antibacterial activities towards Escherichia coli and Staphylococcus aureus. This work supplied a novel way to endow the superhydrophobic and antibacterial properties on wood veneer, and promote its multifunction application.
