摘要

Banana pseudostem fiber (BPF) is a residue-derived lignocellulosic reinforcement with increasing relevance for sustainable composite materials. Reported BPFs contain about 55–65% cellulose, 15–25% hemicellulose, and 10–15% lignin, while raw fibers commonly show tensile strength of about 200–600 MPa and Young’s modulus of about 7–32 GPa, depending on cultivar, extraction route, fiber diameter, conditioning state, and test method. Surface modification is needed because untreated fibers contain hydroxyl-rich constituents, such as pectin and waxes, as well as surface impurities that limit matrix wetting, interfacial adhesion, and moisture durability. This review evaluates extraction routes, surface treatments, structure–property relationships, composite processing, application engineering, durability, and sustainability aspects of BPF composites. Particular attention is given to alkali, silane, acetylation, enzymatic, plasma, and hybrid treatments, with emphasis on treatment conditions, interfacial mechanisms, changes in properties, and application relevance. Current evidence shows that treatment effectiveness depends strongly on reagent concentration, exposure time, temperature, washing, drying, and compatibility with the selected matrix. The main limitations are inconsistent extraction reporting, incomplete treatment protocols, insufficient long-term aging data, limited BPF-specific life cycle assessment (LCA), and weak supply-chain quantification. BPF can be used in lightweight panels, packaging, automotive interior parts, insulation systems, and technical textile products when extraction, treatment, matrix selection, and service environment are matched carefully.
