This paper presents an anticorrosive method to protect bamboo from the corrosion induced by coating a layer of epoxy resin on the surface of bamboo slices. Four surface modifications including heat treatment, alkali treatment, coupling treatment and acetylation treatment are applied to bamboo slices. The results indicate that the ultimate tension of bamboo slices decreases when corroded in solutions with different pH for different time, while epoxy resin protectsthe bamboo slices from corrosion to maintain the tensile properties by coated on its surface.The surface morphology indicates that four modifications have different degrees of influenceon the surface and material of bamboo slices, which can reduce the ultimate tension of bamboo slices, but improve the interfacial combination between the surface of bamboo slices and epoxy resin. Acetylation treatment was the most effective modification analysed by Fourier-transform infrared spectroscopy (FT-IR) among them.
