Abstract：Synthetic polymer materials such as paraformaldehyde and polyamides are widely used in the field of energy engineering. However, they pose a challenge to environmental sustainability because they are derived from petrochemicals that are non-renewable and difficult to degrade in the natural environment. The development of high-performance natural alternatives is clearly emerging as a promising mitigation option. Inspired by natural bamboo, this research reports a "three-step" strategy for the large-scale production of triboelectric materials with special nanostructures from natural bamboo. Benefiting from the special hierarchical porous structure of the material, Bamboo/PANI triboelectric materials can reach short-circuit current of 2.9 μA and output power of 1.1 W m-2 at working area of only 1 cm2, which exceeds most wood fiber-based triboelectric materials. More importantly, it maintains 85% energy harvesting after extreme environmental of high temperature (200°C), low temperature (-196°C), combustion environment and multiple thermal shocks (ΔT=396°C). This is unmatched by current synthetic polymer materials. This work provides new research ideas for the construction and application of biomass structural materials under extreme environmental conditions.
