In order to meet the ever‐increasing demands of complex engineering applications, it is necessary to design the polymer‐based composites with the synergistic improvements in strength and toughness. Herein, the novel carbon nanotubes (CNT)‐bismaleimide (BMI) hybrid construction (CBH) was prepared through mechanical blending and pulverizing. The as‐prepared CBH with a stable structure and well‐regulated morphological construction was employed as a special functional filler to endow the epoxy‐based composites with a significantly enhanced overall mechanical property. Due to CBH can provide a multiscaled interfacial interaction with matrix, the composite loaded with 1 wt% CBH exhibited the synchronously improved both tensile modulus (1.31 GPa) and toughness (1.89 MJ m−3), which are 27.18% and 209.83% higher than those of pure epoxy, respectively. Moreover, good interfacial compatibility between CBH and matrix allows the composite loaded with 1 wt% CBH to exhibit the thermal conductivity of 0.18 W m−1 K−1, which was 28.57% higher than pure epoxy (0.14 W m−1 K−1). Be different from many other CNTs‐loaded counterparts, the aligned‐CNTs loaded composite showed a well‐maintained insulating feature. The novel carbon nanotubes‐polymer hybrid construction expands the application range of epoxy‐based insulating composites by optimizing their mechanical and thermal properties.

The anticorrosion, flame retardant, and mechanical properties of polyurethane (PU) coatings have been improved by the integration of nickel disulfide (NiS2), 2,5‐Bis(4‐aminophenyl)‐1,3,4‐oxadiazole (BAO), and graphene oxide (GO). The structural, morphological, dielectric, and hydrophobic behaviors of the films were characterized for the different formulations of coatings such as pure PU, PU‐NiS2, PU‐BAO/NiS2, PU‐GO/NiS2, and PU‐GO/BAO‐NiS2 (nanocomposite) by means of scanning electron microscope/X‐ray energy dispersive spectroscopy, transmission electron microscope, thermogravimetric analysis, X‐ray photoelectron spectroscopy, X‐ray diffraction, and contact angle measurement. As a result, with the addition of only 0.3% GO/BAO‐NiS2, the dielectric constant of PU was increased by 81‐fold at 1 Hz. Additionally, the nanocomposite had significantly lower peak heat release rate and overall heat released values than pure PU, a difference of 57% and 51%, respectively, demonstrating its greater flame retardancy. The electrochemical techniques and mechanical testing confirmed that GO/BAO‐NiS2 (0.3%) composite exhibit enhanced anticorrosive, hydrophobic, flame retardancy, and mechanical performance of the PU coating. The super hydrophobic behavior is confirmed by its water contact angle of 165°. Furthermore, the resistance of the nanocomposite was found to be much higher (16,985.6 kΩ.cm2) than that of the pure PU (145.4 kΩ.cm2) and the microhardness and tensile strength were increased sharply. Therefore, the nanocomposite could act as a potential coating material for industrial applications.

“…Deicing systems usually adopt mechanical or thermal management methods to remove existing ice. − Electrothermal deicing, the most common deicing measure with strengths such as easy control and low energy consumption, has been widely utilized in windshields, airspeed tubes, fixed wings, and rotor blades. , Thermal deicing is a highly efficient, real-time and adaptive measure to melt off ice by heating up the electrothermal functional layer on the structure surface, which has been the mainstream topic for both research and application currently; however, there are still urgent needs to develop advanced deicing functional materials with optimized properties. Benefiting from their strong affinity with aviation composites, epoxy resin composites are ideal for anti-icing/deicing; − however, since epoxy resin (EP) performs poorly in terms of electrical conductivity and low intrinsic thermal conductivity, an annexing agent is necessary to reinforce its thermal and electrical conductivity.…”

Epoxy resin composites with excellent properties in mechanical and corrosion resistance are widely utilized in aviation, however, the high cost of industrial preparation has been a hindrance for their further application. Therefore, we proposed a simple and economical method to prepare a new type of conductive paint from epoxy resin and reduced graphene oxide composites in concentration gradients. The three-layer gradient concentration paint (TLGCP) possesses good electrical, mechanical, and electrothermal properties. Under the 10 V voltage, the surface temperature of TLGCP rises rapidly to about 120 °C within 100 s, which enables the 2 mm-thick ice layer to melt thoroughly within approximately 250 s at −30 °C. That guarantees the extraordinary deicing effect of TLGCP despite less graphene being utilized. In addition, the resistance of TLGCP almost remains unchanged after 1,000 compression cycles at a strain of 5%, indicating that the interfaces of TLGCP are well connected. The results indicate the great potential of TLGCP for aviation deicing, and its simple and economical preparation renders TLGCP well suited for industrial mass production.
