“…The synthesis of MWCNT-ZnO is described in figures 1 and S3 illustrates the EDX data for MWCNT-ZnO, while figure S4 depicts XRD plots for MWCNT, ZnO, and MWCNT-ZnO. The characteristic peak of MWCNT was around 26.18° [62]. However, the MWCTN characteristic peak in MWCNT-ZnO is not evident, as the nanomaterial is coated with ZnO (figure S1).…”

A new nanomaterial or nano-filler in the form of multiwalled carbon nanotube-zinc oxide (MWCNT-ZnO) was synthesized for the purpose of modifying poly(butylene adipate-coterephthalate) (PBAT) and its derivative (modified PBAT or MPBAT) through a melt-blending method (MPBAT was obtained by introducing maleic anhydride groups into PBAT). The effect of the new nano-filler on the properties of resultant nanocomposites was determined from the characterization of mechanical properties, morphology, crystallinity, thermal stability, barrier properties, hydrophilicity, conductivity, antibacterial property, and biodegradability. The results showed that MPBAT nanocomposites had stronger mechanical properties, better barrier properties, and higher electrical conductivity than PBAT nanocomposites. Scanning electron microscopy illustrated that MWCNT-ZnO had better compatibility with MPBAT than with PBAT. At 0.2% MWCNT-ZnO, the MPBAT/MWCNT-ZnO nanocomposite film exhibited the greatest mechanical properties (17.74% increase in tensile strength, 22.17% in yield strength, and 14.29% in elongation at break). When the MWCNT-ZnO content was 0.4%, the nanocomposite film demonstrated the best water vapor barrier ability (an increase of 30.4%). The MPBAT/MWCNT-ZnO film with 0.6% MWCNT-ZnO turned out to have the best oxygen barrier performance (an increase of 130% relative to pure PBAT). It was shown from the results NanotechnologyNanotechnology 32 (2021) 485706 (17pp)

“…In Figure 2a, for pure PBT, the peak at 1706 cm À1 is assigned to the stretching vibration of the C O group, and the peaks at 1250 and 1101 cm À1 correspond to the stretching of C O groups. 19 The peak at 1217 cm À1 is assigned to covalent C F bonds in FGr. 41 As the FGr content increases in the ternary composites, the C F peak gradually emerges.…”

“…8,9 It is generally accepted that the neat PBT matrix is damaged mainly by adhesive wear initiated by frictional heat generated due to asperity contact, leading to subsequent microcracking. 10,11 The reinforcement mechanism of fillers such as fibers, [12][13][14][15][16][17][18] metal oxides, [19][20][21] clays, 22 and carbon materials 23,24 ranging from the nanometer to micrometer scale have also been reported, and different types of composites have been developed. However, deep-sea working conditions are very harsh.…”

The application of polymer composites is one of the most effective methods for preventing lubrication failure in deep‐sea engineering. In this study, fluorinated graphite (FGr) microsheets were incorporated into polytetrafluoroethylene (PTFE) microparticle‐filled poly(butylene terephthalate) (PBT) composites. The tribological performance in the simulated deep‐sea environment at elevated seawater pressure equivalent to 3000 m ocean depth was investigated. The results showed that FGr enhances the flexural and compressive strengths, thermal stability, and seawater resistance of the PTFE/PBT composite. The wear rate was decreased to 96% at the critical FGr content of 4% by improving the transfer onto the metallic counterfaces, preventing direct contact and shear between friction couples. Moreover, the seawater pressure impedes composite transfer, leading to a 29% increase in the wear rate.

“…[47,48] Besides, Compared with PMAFe0-30% and POE, the morphological characteristics of the fracture surfaces of PMAFe0.1-30% exhibited obviously coarser surface and filiform layered fracture (Figure S7), indicating that the introduction of dynamic crosslinking network achieved higher interface adhesion between PMAFe and POE to improve the fracture resistance. [49,50] Paradoxical, with the increase of the mass of iron(III), the strength and toughness decreased, which could be attributed to the uneven distribution of them caused by overdose iron(III) ions. [45,51] These results showed that the introduction of dynamic crosslinking network could significantly improve the strength and toughness of the composites.…”

The low tensile strength of ethylene/α-octene co-polymer (POE) limits its application as high-strength materials. In this study, 3-amino-1,2,4-triazole (ATA) was grafted onto maleic anhydride functionalized POE (PM) by melt reaction to obtain side chains capable of forming hydrogen bonding and metal coordination bonding, and then ferric chloride hexahydrate and POE are blended with them to obtain composite materials with high strength and fracture energy. The introduction of iron-based coordination bonding and hydrogen bonding double dynamic crosslinking network endow thermoplastic elastomers with excellent mechanical strength and high toughness. Fourier transform infrared spectroscopy, rheological tests, and X-ray photoelectron spectroscopy reveal the existence of non-covalent crosslinking networks. Based on the strengthening and toughening of non-covalent dynamic crosslinking network, the tensile strength of the modified POE elastomer composites achieves 12.5 MPa along with the elongation at break of 3540%. In addition, the modified POE elastomer composites exhibit improved melt elasticity and thermal stability.
