Abstract

The utilization of lignocellulose fibers aligns with with the increasing growing interest in sustainable and renewable materials, offering an eco-friendly alternative to synthetic options. Lignocellulose fibers, such as sugarcane bagasse (SB) and kapok (KF), are biomass rich in chemical functional groups, making them intriguing materials with a pivotal role in the development of new materials for various applications. Our research focuses on the interactions between surfactants and SB or KF, emphasizing the molecular orientation of surfactant molecules on the fiber surface and the properties of the modified fibers. The modification with soy lecithin (SL) or cationic surfactants results in new surfaces, facilitating the development of materials with excellent acoustic absorption properties[1] or improved adsorption capacity for dyes metal ions, and organic contaminants[2-5].
