“…The low roughness of this surface (Ra of 1.7 nm) weakens the mechanical engagement with the asphalt interface. 4 After 24 h of in situ growth, Figure 4D-F,I demonstrate that uniformly sized rhombic dodecahedral NPs (ZIF-67) are densely anchored to the surface of PET fibers. The naked eye can observe the resulting modification as a color change from white to purple.…”

“…5 According to the SHRP specification (T315. AASHTO 2013), 4 various parameters of the original SBS-MA and modified asphalt with differing admixtures of fibers were measured using parallel plates with a diameter of 25 mm and a spacing of 1 mm, within a shear frequency range of 0.1-10 Hz and a scanning temperature range of 46-82 C. The parameters measured included the complex modulus (G*), phase angle (δ), and rutting factor (G*/sinδ). The G* reflects the ability of the asphalt binder to resist shear deformation, 5 while δ represents the proportion of viscous and elastic components of the binder.…”

“…The multiple stress creep recovery (MSCR) test was used to further evaluate the rutting resistance of the modified asphalt. 4 Based on ASTM D7405 37 operating procedures, the entire test was performed at a constant temperature of 64 C and pressure of 0.1 and 3.2 kPa for 1 s, followed by an unstressed recovery period of 9 s. This process comprised 10 creep and recovery cycles at both stress levels.…”

“…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.…”

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.

“…Electrospinning is a feasible and cost-effective method for mass-producing thin polymer films and fiber mats. [26][27][28][29][30][31][32] On the other hand, the electrospinning process mostly utilized to manufacture biocompatible polymers for tissue engineering and biomedical applications since it can swiftly produce biopolymer fibers without creating any changes in the polymeric structure. [33][34][35][36][37][38] This method's operating mechanism begins with the creation of a stable solution.…”

In this study, 1 wt% boron carbide (B4C) reinforced PVA nanofibers were fabricated by the electrospinning technique as a new generation of ultra‐thin, lightweight, and flexible neutron shielding nanocomposites. The influence of B4C particles' size and morphology on the fiber formation and radiation shielding performance of fiber mats was investigated. The results indicate that the particle characteristics have a dramatic influence on the formation and properties of nanocomposites. The thicknesses of individual fibers reinforced with sol–gel synthesized nano‐sized boron carbide particles were in the range of 50–250 nm, while those containing commercial B4C powder were produced in the thickness range of 1–2 μm. In contrast to the commercial particles, the sol–gel synthesized nano B4C particles enhanced the fiber mat's density and the roundness of individual fibers. Both theoretical and experimental radiation shielding studies showed that B4C reinforcement successfully improved the neutron and gamma attenuation of the neat PVA matrix. Furthermore, it was found that a 6.5 mm thick PVA nanofiber mat, reinforced with only 1 wt% B4C nanoparticles shielded up to about 7.4% of the initial neutron flux. Compared to the neat PVA fiber mat, reinforcement of PVA fibers with 1 wt% sol–gel synthesized nano‐sized boron carbide particles enhanced the neutron shielding by 50.31%. Moreover, even though B4C is not an effective gamma shielding reinforcement, the amplified density of nanocomposite fiber mats also enhanced gamma attenuation.

Conductive composite nanofibers are promising materials, especially wearable strain sensors, due to their lightweight, breathability, flexibility, and skin affinity. Here, we propose a dual‐conductive network by the sequential decoration of amin‐modified boron nitride nanosheets (BN), copper nanoparticles (Cu), and polyaniline (PANI) into the elastic thermoplastic polyacrylonitrile (PAN) nanofiber. The Cu nanoparticles/BN‐enwrapped PANI nanocomposite was synthesized using successive environmentally friendly reduction and chemical oxidation polymerization. First, Cu (II) ions were immobilized on modified BN and reduced with L‐ascorbic acid (BN@Cu), followed by a chemical oxidation polymerization of aniline using ammonium persulfate as an initiator (BN@Cu/PANI). The XRD (X‐ray diffraction), FTIR (Fourier Transform Infrared Spectroscopy), SEM (Scanning Electron Microscopy), and TEM/EDXS (Transmission Electron Microscopy/Energy Dispersive X‐ray Spectroscopy) analysis confirmed the coexistence of the BN@Cu/PANI phase and composition. The DC electrical conductivity of BN@Cu/PANI nanocomposite (0.567 S/cm) was quietly higher than PANI (0.167 S/cm) and BN@Cu (0.077 S/cm). The thermal conductivity of BN@Cu and BN@Cu/PANI was 0.626 and 0.444 W/mK, respectively. The BN@Cu/PANI loaded‐PAN composite nanofibers were successfully produced by electrospinning. SEM studies confirmed that the composite nanofibers have uniform fiber structure and suitable BN@Cu/PANI dispersion/distribution within the PAN. BN@Cu/PANI‐reinforced PAN nanofibers showed a 2‐fold decrease in the specific heat capacity and a 50‐fold increase in electrical conductivity of the nanofibers at 10 wt%BN@Cu/PANI loading. This work offers dual‐conductive polymer‐based composites, which can be used in thermal management applications in microelectronics devices.Highlights The dual‐conductive nanocomposite, BN@Cu/PANI, was prepared a simple, low‐cost method. BN@Cu/PANI, core/shell nanocomposite, was easily produced this way for the first time. BN@Cu nanoparticles increased the polymerization rate of PANI. The thermal and electrical conductivity of BN@Cu/PANI was 0.444 W/mK and 0.567 S/cm. Electrical conductivity of BN@Cu/PANI‐PAN increased 50‐fold increase at 10 wt%BN@Cu/PANI.
