Abstract
AbstractIn this study, a novel multiscale synergistic reinforced polyester fiber (PET) was prepared by a bionic coating and electrostatic synergism. The three‐dimensional (3D) interconnected structure was developed on the surface of PET by electrostatically synergistic hybridization of negatively charged 2D lamellar graphene oxide (GO) and positively charged 1D hollow tubular aminated halloysite nanotubes (HNT). These fibers were applied to prepare fiber incorporated styrene‐butadiene‐styrene modified asphalt (SBS@MA). X‐ray photoelectron spectroscopy, atomic force microscopy, and field emission scanning electron microscopy analyses revealed that the 3D interconnected highly rough structure was constructed on the fiber surface. The surface free energy and adhesion work at the fiber and asphalt were calculated from the contact angle tests, which showed that adhesion work of the modified fibers was improved by 30% compared with the original fibers, confirming the better adhesion performance of GO‐mHNT‐PET fibers with the asphalt. The improved mechanical and viscoelastic characteristics of the modified GO‐mHNT‐PET/SBS@MA were verified by dynamic shear rheometer, and multistress creep recovery tests. At 46°C, the complex modulus of 1.5% GO‐mHNT‐PET/SBS@MA was 31.02% higher compared with that of PET/SBS@MA. This study provides a promising strategy for the preparation of PET/SBS@MA materials with excellent mechanical properties and interfacial bonding.
