This invention discloses a thermally induced responsive self-healing superhydrophobic bamboo material and its preparation and self-healing methods. The preparation method utilizes a
sol-
gel method to prepare a superhydrophobic
prepolymer, which is then impregnated with the bamboo material to obtain the superhydrophobic bamboo material. This invention not only assembles a
superhydrophobic coating on the surface of the bamboo material through vacuum impregnation but also permeates the bamboo material with the superhydrophobic
prepolymer, providing a foundation for the self-healing of the superhydrophobic bamboo material after damage. The preparation method has advantages such as simple operation, short preparation cycle, and effective improvement of the protective performance and durability of the bamboo surface. It is of great significance for improving the surface properties and
functional expansion of bamboo, as well as the long-term use of durable superhydrophobic bamboo materials.
