文摘

A facile sonication route to produce aqueous wax dispersions is developed. The wax dispersion is naturally stable and free of surfactants or stabilizers. Wax and ZnO particles are coated onto wood using layer-by-layer assembly. The coating brings superhydrophobicity while preserving moisture buffering. ZnO improves the color stability of wood to UV light.
