advanced materials with natural hierarchical structures have attracted considerable attention from researchers. [18][19][20][21][22][23][24] As an inexhaustible and sustainable resource, biomass materials show advantages in the development of highperformance structural materials due to their special hierarchical and porous structure. [25][26][27][28][29] The highly ordered hierarchical structure provides strong mechanical support for plant growth and promotes the vertical transportation of nutrients. The natural pore structure provides a channel for the exchange of material between adjacent cells and improves the energy storage efficiency of plants. [30,31] Inspired by this interesting organizational structure, researchers have developed composite advanced materials based on natural cellulose scaffolds, which is attracting attention in many fields such as energy storage, smart wearable electronics, [32][33][34] especially in the field of distributed micro-nano energy harvesting due to its special structure and excellent performance. [31,35] However, most bio-based composite materials still suffer from high-temperature decomposition, low-temperature brittleness, and even material decomposition, which severely limits their expansion and application in polar exploration, aerospace, and other extreme conditions. Therefore, it is still a great challenge to develop triboelectric functional materials with high efficiency, environmental stability, and rich sensing types.Compared with other biomass materials, bamboo, as a natural composite material, has a special functional gradient, in which the main components include lignin and cellulose. [36] In bamboo, fiber cells with various orientations composed of cellulose transport sufficient nutrients for the growth of lignin, while lignin provides adhesion and physical defense for the growth of fiber cells. Inspired by the "mutual benefit and winwin" model of natural bamboo, this research reports a simple and mild "three-step" strategy to the in situ growth of polyaniline (PANI) in bulk bamboo-derived cellulose scaffolds to construct hierarchical porous Bamboo/PANI triboelectric materials (BPTM) with continuous conductive pathways. The hierarchical porous cellulose scaffold constructed in this work enables abundant nucleation sites for the growth of PANI without complicated processes. Additionally, the hierarchical porous structure derived from natural bamboo allows the triboelectric charge to be distributed not only on the contact surface but also 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 ...

Lead ion (Pb2+) is one of the most common water pollutants. Herein, with bamboo as the raw material, we fabricate a thin-walled hollow ellipsoidal carbon-based adsorbent (CPCs900) containing abundant O-containing groups and carbon defects and having a specific surface area as large as 730.87 m2 g–1. CPCs900 shows a capacity of 37.26 mg g–1 for adsorbing Pb2+ in water and an efficiency of 98.13% for removing Pb2+ from water. This is much better than the activated carbon commonly used for removing Pb2+ from water (12.19 mg g–1, 30.48%). The bond interaction of Pb2+ with the O-containing groups on CPCs900 and the electrostatic interaction of Pb2+ with the electron-rich carbon defects on CPCs900 could be the main forces to drive Pb2+ adsorption on CPCs900. The outstanding adsorption performance of CPCs900 could be due to the abundant O-containing groups and carbon defects as well as the large specific surface area of CPCs900. Bamboo has a large reserve and a low price. The present work successfully converts bamboo into adsorbents with outstanding performances in removing Pb2+ from water. This is of great significance for meeting the huge industrial demand on highly efficient adsorbents for removing toxic metal ions from water.

Lightweight polymer composites promise incredible applications in aerospace, seaprobes, and medical apparatus. However, their performance is generally limited by a trade‐off between mechanical strength and toughness. Herein, a crystallinity mitigating strategy driven by highly aligned bamboo macrofibers embedded in a polycaprolactone polyol (PCL) matrix for producing ultrastrong and tough lightweight polymer composites is proposed. The embedded bamboo macrofibers have oxygen‐containing functional groups on the fiber surface, that can interact with functional groups (ester and hydroxyl groups) in the molecular chains of the PCL in the form of hydrogen bonds, thus preventing the aggregation of molecular chains and the crystallization of PCL, which ultimately leads to unprecedented toughness. Meanwhile, the bamboo macrofibres with intrinsically aligned microstructure, can enable effective stress transfer and dissipation, providing remarkable ultrahigh strength. As a result, the obtained lightweight polymer composite achieves ultrahigh mechanical strength (31.5 MPa) and superior toughness (21.7 MJ m−3) at an unprecedented low density (1.07 g cm−3), representing the state‐of‐the‐art in reported lightweight polymers. Such lightweight polymer composite has the potential to greatly expedite the practical realization of artificial medical materials, including orthopedic instruments and joint prostheses.
