A Multilayer Transparent Bamboo with Good Optical Properties and UV Shielding Prepared by Different Lamination Methods

Transparent bamboo (TB) is a new type of biomass and light-transmitting material. However, due to the high density of bamboo, it is arduous for polymers to impregnate the bamboo, and the thickness of bamboo becomes a key factor limiting the development of transparent bamboo. Here, inspired by plywood, we report a multilayer transparent bamboo (MLTB). The aim of this experiment is to study the performance of MLTB under different lamination methods, including the influence of the number of layers and lamination direction. It was found that there were different effects caused by lamination combination on the optical and mechanical properties of MLTB. Meanwhile, the obvious anisotropy of TB is effectively improved due to the laminated structure. It was found that the mechanical and optical properties of MLTB can be effectively adjusted by different assembly methods. The obtained MLTB combines high strength, good hydrophobicity, unique texture appearance, high light transmittance, and excellent resistance to ultraviolet rays simultaneously. It has broad prospects for practical application in the fields of home decoration, construction, structural materials, etc.
