“…This is primarily attributed to the physical entanglement of PET fiber and the asphalt phase's adsorption, the adhesion between the interfaces, the synergistic 3D network structure and the mechanical interlocking effect, which impeded the flow of bitumen and enhances the adhesion and toughness of the bitumen binder. 49 The graph displays the values of G 0 and G 00 at a given temperature and a frequency of 10 Hz in an order of: SBSMA < PET/SBS@MA < GO-PET/SBS@MA < GO-mHNT-PET/SBS@MA. Notably, the G 0 of SBS@MA blended with 1.5% GO-PET fiber was 12.43% higher at 46 C than that of SBS@MA blended with 1.5% PET fiber, while the G 0 of SBS@MA blended with 1.5% GO-mHNT-PET fiber was 17.48% higher.…”

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.

“…5 Moreover, the inclusion of a ZIF-67 nanocrystalline interfacial layer between the fibers and bitumen enhances their interfacial adhesion and promotes the interfacial effect of elastic components in bitumen, facilitating the transmission of external forces to micro-and nanostructures. 4,6 Consequently, this effectively strengthened the interfacial bonding between dispersed and continuous phases, facilitating more efficient stress transfer and positively impacting the resistance of asphalt binders to rutting and shear deformation.…”

“…20,23 Second, ZIF-67 demonstrates a range of active metal-ligand centers and functional groups, allowing the utilization of accessible active sites to enhance interfacial interactions between the fibers and matrix asphalt, thus potentially improving the mechanical and rheological properties of modified asphalt composites. 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.…”

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.

This study addresses disposable medical mask (DMM) environmental issues through recycling polypropylene fibers. Polypropylene fibers were collected from DMMs, artificially crush them, and enhance fiber–cement interaction via advanced Fenton oxidation. Analysis (Fourier transform infrared spectrometer, x‐ray photoelectron spectrometer, field emission scanning electron microscope (FE‐SEM), energy‐dispersive x‐ray spectrometer, atomic force microscope, contact angle) confirms successful FeOOH grafting onto M‐DMM fibers, increasing roughness and wettability. Compared with DMM fibers, the surface free energy of M‐DMM fibers increased by 46.3%. Consequently, the grafting of FeOOH onto the fiber surface improves the physical friction and interlocking effects between the fibers and cement. FE‐SEM results after 28 days of curing reveal that M‐DMM fibers exhibit better bonding ability with cement compared with unmodified DMM fibers. Mechanical tests unequivocally demonstrated the enhanced impact resistance of the cement mortar incorporating M‐DMM fibers compared to the reference. Specifically, there was a significant 16.0% increase at 7 days of curing, followed by an additional 4.5% improvement after 28 days of curing. This study provides an eco‐friendly solution for addressing the post‐pandemic surge in DMM waste, reducing microplastic pollution, and lowering disposal costs. It also offers the construction industry an innovative material enhancing cement mortar's impact resistance, aligning with sustainable development principles.
