“…The PDA-PET fibers, which offer active sites through forming a PDA layer via self-polymerization, exhibit a distinct peak at 1382 cm À1 compared to the pristine PET fibers, which is attributed to the C-N bonding from PDA. 8 Furthermore, Figure S3 depicts a comparison of the infrared spectra between ZIF-67 nanocrystals and the modified fiber. Most distinctive peaks observed in ZIF-67-PDA-PET fibers are related to the imidazole ring of 2-methylimidazole present in ZIF-67.…”

“…Incorporating PET fibers into SBS-MA forms a 3D network structure that partially restricts slip deformation of asphalt binder under external forces. 8 However, due to the chemically inert and smooth surface of PET fibers, adhesion with asphalt is insufficient and the number of active sites is limited. 10 Therefore, introducing a nanoporous structural reinforcement layer of ZIFs is necessary to optimize interfacial interactions and properties.…”

“…Moreover, their chemical composition is similar to asphalt components, making them highly attractive for asphalt pavement applications. 8 Furthermore, given that asphalt is a highly viscous fluid derived from residues of petroleum distillation, 9 fibers added to asphalt-based composites can serve as crack arrestors, adsorbers, stiffeners, and stabilizers, 5 which can in turn enhance the overall performance of the final material. However, the smooth surface and chemical inertness 10 of the PET fibers lead to a weak interface with asphalt, making the fibers highly susceptible to interfacial debonding and pull-out.…”

“…6,19 The chemically inert and smooth morphology of the PET fiber substrate surface makes it challenging to bind synthesized ZIF-67 nanocrystals directly to the polymer fiber substrate. 8 Contrary to oxidation, acid and alkali etching treatments, and plasma treatments to activate the fiber surface, the approach of fiber sizing or coating emerges as a more convenient and effective strategy. [11][12][13]24 Importantly, this method safeguards the integrity of both the fiber surface and its mechanical strength.…”

Utilizing efficient and cost‐effective modifiers is essential for the development of high‐performance asphalt materials. In this study, a polydopamine (PDA) chelated cobalt ion (Co2+)‐assisted in situ growth strategy was employed to anchor nanoporous zeolite imidazolium salt framework‐67 (ZIF‐67) on polyester (PET) fiber substrates for the preparation of styrene‐butadiene‐styrene block copolymer‐modified asphalt (SBS‐MA). Experimental results indicated that optimal fiber incorporation of 1.5% led to the best interfacial interaction at the modified asphalt fracture section. ZIF‐67 nanoporous structure acted as an organic–inorganic hybridization interfacial layer to enhance the fiber–asphalt interfacial interaction. The adhesion work of the modified fiber with SBS‐MA increased by 42.12%. Furthermore, the adhesion work, peeling work, and compatibility ratio of modified asphalt with aggregates were also improved. Similarly, the complex modulus of the 1.5% ZIF‐67–PDA–PET/SBS‐MA at 46°C was increased by 131.30% in comparison with that of the pristine SBS‐MA. More importantly, the synergistic effect of the highly thermally stable PET fibers and ZIF‐67 nanocrystals improved the thermal decomposition of SBS‐MA. These results suggest that ZIF‐67–PDA–PET fiber holds great promise for application in designing novel materials for the construction industry.

In 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.

Based on the high chemical stability and excellent end‐group functionalization capability of polyhedral oligomeric silsesquioxane (POSS), this study utilized thiol‐functionalized POSS (POSS‐SH) in a click chemistry reaction with styrene‐butadiene‐styrene triblock copolymer (SBS). The objective was to design a functional group forming a chemical bond with the polymer matrix, resulting in the preparation of thiol‐functionalized polyacrylonitrile (PAN) fibers chemically cross‐linked with POSS‐SH/PAN/SBS hybrid material. This hybrid material not only enhanced the compatibility between the components but also facilitated a connection between the fiber and SBS, thereby improving the mechanical properties of the modified asphalt. Fourier transform infrared spectroscopy, field emission scanning electron microscopy (FESEM), and atomic force microscopy analyses confirmed the successful modification of POSS‐SH/PAN fibers. FESEM analysis of the modified asphalt verified that POSS‐SH/PAN fibers contributed to strengthening the interfacial performance between the fiber and asphalt. Cone penetration and dynamic shear rheometer tests indicated that, compared to SBS‐modified asphalt, PAN/SBS and POSS‐SH/PAN/SBS‐modified asphalt exhibited enhanced shear strength, deformation resistance, and viscoelastic properties. Additionally, at 46°C, the storage modulus (G′) of 1.5% POSS‐SH/PAN/SBS‐modified asphalt increased by 11% compared to 1.5% PAN/SBS asphalt, with increases of 13.75% and 10.8% in loss modulus (G″) and complex modulus (G*), respectively.
