Bamboo with single-sided densification on bamboo inner layer, and preparation method and use thereof

A method for preparing a bamboo with single-sided densification on a bamboo inner layer, comprising:

• placing the bamboo inner layer of the bamboo in an impregnation solution, and conducting an impregnation treatment to obtain an impregnated bamboo;
• wherein the impregnation solution comprises one selected from the group consisting of water and a flame retardant solution;
• subjecting a resulting bamboo inner layer of the impregnated bamboo to a preheating and softening treatment to obtain a preheated and softened bamboo;
• maintaining a temperature for the preheating and softening treatment of the resulting bamboo inner layer, while subjecting the preheated and softened bamboo to pressurization and compression to densify the bamboo to a target thickness, to obtain a compressed bamboo;
• and
• simultaneously subjecting a resulting bamboo inner layer and a bamboo outer layer of the compressed bamboo to a hot pressing and shaping treatment, and subjecting a resulting bamboo to cooling and depressurizing in sequence to obtain the bamboo with single-sided densification on the bamboo inner layer.
