The use of two-dimensional graphene as a versatile platform for anchoring target molecules that confer and convey specific properties in a robust and effective way to textile fabrics through covalent modification is demonstrated. Specifically, we carried out the functionalization of graphene oxide (GO) with melamine, and in parallel, we chemically modified Kevlar with a tracer molecule, easily monitored through various techniques, including IR spectroscopy, thermogravimetric analysis, and the Kaiser test. The resulting modified Kevlar possesses free amines that subsequently condense with GO-melamine material, furnishing the covalently linked Kevlar-GO-melamine hybrid multifunctional material/fabric, where the melamine's UV-light protection quality and the antibacterial properties of GO are effectively transferred to Kevlar, which also retains its unique mechanical properties. The newly developed multifunctional material holds promise for various applications, capitalizing on its combined strength and multifaceted protective attributes.

凯夫拉尔与氧化石墨烯-三聚氰胺的共价后功能化，具有紫外线防护和抗菌性能

展示了使用二维石墨烯作为锚定目标分子的多功能平台，通过共价修饰以稳健有效的方式赋予和传递特定性能给纺织面料。具体来说，我们用三聚氰胺对氧化石墨烯（GO）进行了功能化，同时，我们用示踪分子对 Kevlar 进行了化学修饰，可以通过各种技术轻松监测，包括红外光谱、热重分析和 Kaiser 测试。所得改性 Kevlar 具有游离胺，随后与 GO-三聚氰胺材料缩合，形成共价连接的 Kevlar-GO-三聚氰胺杂化多功能材料/织物，其中三聚氰胺的紫外线防护性能和 GO 的抗菌性能有效地转移到 Kevlar 上，还保留了其独特的机械性能。新开发的多功能材料利用其综合强度和多方面的保护属性，有望实现各种应用。
