A novel method of constructing nanostructures on the surface of aramid fiber (AF) was demonstrated in this article. Through the π–π* interaction between the aramid nanofiber (ANF) and graphene (G), the G/ANF dispersion stably existed in water. In an alkaline solution of tannic acid (TA) and polyethyleneimine (PEI), a TA/PEI (TP) layer was deposited on the surface of AF to introduce functional groups. Then, the modified AF was impregnated with the G/ANF dispersion to construct surface nanostructures to enhance the interfacial adhesion between the fiber and rubber. The results showed that the H pull-out force of the AF and rubber after impregnating with G, ANF, and G/ANF was increased by 15.3, 21.5, and 84.7%, respectively, compared with the untreated AF. The Raman spectroscopy and SEM results show that there is a π–π* interaction between G and ANF, and the ANFs are firmly attached to the surface of G. The hybrid G/ANF nanofiller can form 3D nanostructures on the surface of AF to improve the mechanical interlocking and stress transfer between the fiber and the rubber matrix, thereby achieving excellent interfacial adhesion while maintaining the excellent mechanical properties of AF.

石墨烯/芳族聚酰胺纳米纤维杂化材料对芳族聚酰胺纤维进行表面涂层，以增强与橡胶基体的界面粘合力
本文介绍了一种在芳纶纤维（AF）表面构建纳米结构的新方法。通过芳族聚酰胺纳米纤维（ANF）和石墨烯（G）之间的π–π *相互作用，G / ANF分散液在水中稳定存在。在单宁酸（TA）和聚乙烯亚胺（PEI）的碱性溶液中，TA / PEI（TP）层沉积在AF表面上以引入官能团。然后，将改性的AF用G / ANF分散液浸渍，以构建表面纳米结构，以增强纤维与橡胶之间的界面粘合力。结果表明，与未处理的AF相比，AF和橡胶浸渍G，ANF和G / ANF后的H拔出力分别增加了15.3、21.5和84.7％。拉曼光谱和SEM结果表明，G和ANF之间存在π–π *相互作用，
