“…CTAB-Mica with irregular lamellar structures stacked together, and the layers partly dispersed and stripped, indicating that the initial exfoliation was successfully achieved after the intercalation of CTAB. Undergoing ultrasonic treatment, the size of the mica flakes decreased dramatically (Figure d), and the flakes deposited together to form a thin layer due to the van der Waals forces and large specific surface area of exfoliated MNSs . Individual lamellae displayed typical sheet-like morphology with a much smaller lateral dimension, suggesting that NGM had been converted into small nanosheets (Figure e).…”

An anticorrosive coating with randomly distributed passive barriers and regionally enriched active corrosion inhibitors is developed by integrating mica nanosheets (MNSs) and magnetic-responsive core–shell mesoporous nanoparticles with 2-mercaptobenzothiazole (Fe3O4@mSiO2/MBT) under magnetic field incubation. The bottom enriched Fe3O4@mSiO2/MBT rapidly releases the MBT to form a passivation layer on corrosion sites, enhancing the corrosion inhibition efficiency by 30.36% compared with the control (NP0.7EP-R). The impedance modulus |Z|0.01 Hz of the sample (NP0.7/MNS0.5/EP) increases by five orders of magnitude compared with that of its control (NP0.7/MNS0EP) after 30 days of corrosion immersion. NP0.7/MNS0.5/EP exhibited the lowest corrosion rate (3.984 × 10–5 mm/year) as compared to the other samples. Notably, the coating in a fractured state still maintains superior corrosion inhibition even after 40 day salt spray testing. The differentiated distribution of nanofillers was well confirmed by optical microscopy and SEM-EDS, and the synergistic effect of the active/passive integrated anticorrosive coating with merits of both comprehensive protection and fast responsiveness was systematically explored.

“…Kui Wang et al modified carbon fiber's surface (PDA‐CF) through polydopamine, as well chemically grafted functional hexagonal boron nitride (F‐BN) nano sheet to enhance the interfacial adhesion strength between the epoxy resin (EP) and fiber. When compared to pure EP, the friction coefficient and wear rate of the EP/BN@CF composite are both lowered by 37.8% and 83.0%, respectively 27 …”

“…Inorganic fibers are basic load‐bearing units owing to their superior strength and superior wear resistance 24,25 . They can share the majority of the load during the wear process to protect the matrix from grievous wear, resulting in a low composite wear rate 26,27 . Jingfu Song et al prepared a composite material containing oxidized CF coated with hydroxylated carbon nanotubes (CNTs) and polyimide (PI) by chemical method, and compared to the pure PI, the friction coefficient and wear rate of CF‐CNTs/PI composites declined by 23.2% and 55.9%, respectively 24 .…”

The synergistic effects of carbon fiber (CF) and polytetrafluoroethylene (PTFE) on the friction and wear behavior of polyarylene ether nitrile (PEN) under dry lubrication condition were studied. According to the scanning electron microscopy (SEM) on the composites' surface after wear, the wear mechanism of the composites under dry sliding condition was analyzed. The research results show that the addition of solid lubricants PTFE and carbon fibers to PEN helps to enhance the properties of friction and wear. The specific wear rate is decreased to 5.7 × 10−7 mm3/N m at a PTFE composition of 5 wt%, which is optimized by 33.4% more than PEN/CF composites. In addition, wear mechanisms are mainly abrasive wear, accompanied by adhesive wear and plowing of the friction ring.

“…Guo et al 30 revealed that BN‐CF/polyurethane (PU) composites had the highest dielectric constant increasing to 16.73 with 1 wt% BN and 14 wt% CF, which was 2.14 times of BN (15 wt%)/PU composites and 1.12 times of CF (15 wt%)/PU composites at the frequency of 1 KHz. Wang et al 33 chemically grafted h‐BN nanosheets onto carbon fiber (CF) in epoxy resins (EP) to realize a 13.8% increment in tensile strength and 87.2% in interfacial shear strength (IFSS), a 37.8% reduction in coefficient of friction and 83.0% reduction in wear rate. Zhang et al 34 demonstrated that the thermal conductivity of polycarbonate (PC)/BN composites was 1.38 W/(m·K) with 30 wt% BN, and then increased by 14.5% with further adding 7 wt% CF.…”

It is well known that carbon fiber (CF) reinforced PEEK (polyether‐ether‐ketone) (defined as “PEEK/CF”) composites have excellent properties and have been widely used in diverse fields. Meanwhile, hexagonal boron nitride (h‐BN), as an excellent nano reinforcing agent, is often incorporated into polymer to improve its mechanical strength and thermal conductivity. Herein, PEEK matrix was regulated by adding high‐strength CF as the load‐bearing phase and 2D h‐BN sheets as the solid lubricant and thermally conductive fillers prepared by melt blending to achieve the multi‐scale packing of uniform mixing. The results show that h‐BN is well dispersed in PEEK matrix and improves the interfacial bonding between CF and PEEK matrix, exhibiting a good synergistic effect in enhancing tensile properties of composites. PEEK composite with 20 wt% CF and 4 wt% h‐BN (referred as P/20C/4B) exhibits the highest tensile strength (176.05 MPa) and thermal conductivity (0.396 W/(m·K)), which are 97.54% and 126.3% over those of pure PEEK (89.12 MPa; 0.175 W/(m·K)), respectively. In addition, PEEK composite with 10 wt% CF and 4 wt% h‐BN (referred as P/10C/4B) has excellent tribological properties with a friction coefficient of 0.15, the lowest fiction temperature (30.5°C) and a relative low wear rate of 1.62 × 10−6 mm3/(N·m) among them. The synergitic effects of h‐BN and CF on mechanical, tribological properties and thermal conductivity of PEEK composites provides a very broad prospect in their application of low frictional and wear resistant polymeric materials.
