摘要：
The exceptional mechanical properties of aramid fibers make them a popular choice for high-performance materials; despite that, their potential is limited due to their surface properties bonding energy and interfacial bonding strength with matrix materials. The enhanced resistance of poly-aramid fibers (AFs) to severe surroundings and improved interlaminar adhesion in sandwich compounds with admirable mechanical characteristics are becoming a great challenge for various chemical and physical surface treatment techniques. Supercritical carbon dioxide (scCO(2)) is a popular and sustainable approach that can effectively bond and homogeneously deposit functional groups or nanoparticles and exhibit the excellent performance of fibber modification. This article examines aramid fibers' surface modification advancements using scCO(2)-assisted techniques, including monomer grafting, impregnation, and functionalization with various functional groups and nanoparticles. Additionally, the article discusses the challenges faced in scCO(2)-assisted aramid fiber modification and what the future holds for this technology.
