摘要：Bamboo is widely scattered, rapidly regenerable, and takes on the advantage of long cellulose fibers, which makes it one of the most lightweight and strong natural materials. Scalable processing bamboo into high-performance structural material for plastic replacement is highly promising but challenging. Here, we report a sustainable, high-performance structural material derived from natural bamboo with superior mechanical and thermal properties that benefited from the rational design by the introduction of surface charge and further layer-by-layer assembly of bamboo fibers. The obtained modified bamboo fiber plate (MBFP) transcends the constraints of the natural size and anisotropy for bamboo, while showing high flexural strength (~179 MPa) and flexural modulus (~12 GPa). Meanwhile, the product has an extremely low coefficient of thermal expansion (~12.25 ppm K?1), high thermal stability, and superior fire retardancy. The excellent mechanical and thermal properties combined with the rapid, scalable manufacturing process make the MBFP a powerful plastic alternative in the furniture, construction, and automotive industries. ? 2022, The Authors.
