dc.description.abstractUltra-high-molecular weight polyethylene (UHMWPE) fibers are valued for their high strength-to-weight ratio and are employed in a wide variety of commercial applications. However, because of its low surface energy, UHMWPE can fail in certain applications, such as fiber-reinforced composites. This is due to its poor interfacial adhesion with polar matrices, making it challenging to incorporate into composites and/or retain polar dyes or colorants. Herein, we describe the use of polyamine primers for coating UHMWPE weaves, covalently bonding the aliphatic chains through C−H insertion, leading to strong covalent interactions between fabric and polyamines. We further demonstrate that the polyamine-coated UHMWPE surfaces can successfully react with epoxy resin through nucleophilic addition reactions to enable the production of epoxy composites. Furthermore, we show the use of polyamine-coated UHMWPE in secondary functionalization with amine-reactive compounds, such as dyes, through covalent linkages that result in very strong color fastness.
