Multifunctional Bamboo Fiber/Epoxy Composites Featuring Integrated Superhydrophobicity and Enhanced Mechanical-Thermal Performance.

ABSTRACT: Developing sustainable, high-performance biomass composites is crucial for replacing non-renewable structural materials. In this study, a "bamboo steel" composite was fabricated using a multilevel modification strategy involving alkali pretreatment, toughened resin impregnation, and surface functionalization. Bamboo fibers were treated to remove hemicellulose and lignin, enhancing porosity and interfacial bonding. The bamboo scaffold was subsequently impregnated with a thermo-plastic polyurethane-modified epoxy resin to create a robust, interpenetrating network. The optimized composite (treated at 80 °C) exhibited a flexural strength of 443.97 MPa and a tensile strength of 324.14 MPa, demonstrating exceptional stiffness and toughness. Furthermore, a superhydrophobic coating incorporating s
