Highly Tunable Interfacial Adhesion of Glass Fiber by Hybrid Multilayers of Graphene Oxide and Aramid Nanofiber |
| 초록 |
We present a novel layer-by-layer (LbL) assembly for the surface modification of glass fiber to enhance the interfacial properties between the glass fiber and epoxy matrix. Solution-processable graphene oxide (GO) and an aramid nanofiber (ANF) were employed as active components for the LbL assembly onto the glass fiber owing to their abundant functional groups and mechanical properties. We found that the interfacial properties of the glass fibers uniformly coated with GO and ANF multilayers, such as surface free energy and interfacial shear strength, were improved by 23.6% and 39.2%, respectively, compared with those of the bare glass fiber. In addition, the interfacial adhesion interactions between the glass fiber and epoxy matrix were highly tunable simply by changing the composition and the architecture of layers, taking the advantages of versatility of the LbL assembly. |
