Progress on the preparation of biomass porous carbon and its application in functional textiles

Abstract With the demand for sustainable development, functional textiles like electromagnetic shielding, self‐cleaning, antibacterial, and flame retardant textiles have become a key area of innovation and development in the textile industry. Owing to its renewability, high specific surface area (SSA), and adjustable pore structure, biomass‐derived porous carbon (BPC) has emerged as a pivotal material for replacing petroleum‐based functional materials and facilitating the green upgrading of functional textiles. This review systematically introduces the multifaceted preparation strategy of BPC and focuses on its application in electromagnetic interference shielding, self‐cleaning, antimicrobial, flame‐retardant, and smart textiles. In addition, the study outlines the difficulties encountered by BPC materials in multifunctional textile applications. From the perspectives of green chemical synthesis pathways and interdisciplinary technology integration, this review looks forward to the low‐carbon production and smart application scenarios of BPC materials within the domain of multifunctional textiles. Theoretical references and technological pathways are provided for the sustainable development of the textile industry.
