“…The surface roughness (R a ) was tested by a Mg alloy surface had occurred. 33,34 A significant rise in peak intensity could be seen at 2920 and 2850 cm À1 , which corresponded to the asymmetric vibration peak and the symmetric stretching vibration peak of CH 2 , 35,36 respectively. It was due to the increase of chain length, which enhanced the density of CH 2 in the dual-component silane films.…”

In this paper, the dual-component silane films composed of trimethoxysilane and bis [3-(triethoxysilyl)propyl]tetrasulfide (BTESPT) were prepared on the surface of AZ31B Mg alloys. The selected trimethoxysilanes had different chain length. The results showed that the dual-component silane films could effectively enhance the corrosion resistance of Mg alloys. Moreover, with the enlarging of the chain length of trimethoxysilane, the hydrophobic property and the corrosion resistance of the dual-component silane films were enhanced. And the dual-component silane film composed of BTESPT and octadecyltrimethoxysilane (OTMS) showed the highest contact angle and the best corrosion resistance. It could be ascribed to the high density of CH 2 groups and -S-S-S-Sin the dual-component silane film, greatly improving the hydrophobicity and the anticorrosion property. Simultaneously, the substantial Si-O-Si network in the dual-component silane film also enlarged the length of the penetration paths for corrosive media, delaying the corrosion of the Mg alloy.

Graphene quantum dots (GQD) is an efficient nanomaterial composed of one or more layers of graphene with unique properties that combine both graphene and carbon dots (CDs). It can be synthesized using carbon-rich materials as precursors, such as graphite, macromolecules polysaccharides, and fullerene. This contribution emphasizes the utilization of GQD-based materials in the fields of sensing, bioimaging, energy storage, and corrosion inhibitors. Inspired by these numerous applications, various synthetic approaches have been developed to design and fabricate GQD, particularly bottom-up and top-down processes. In this context, the prime goal of this review is to emphasize possible eco-friendly and sustainable methodologies that have been successfully employed in the fabrication of GQDs. Furthermore, the fundamental and experimental aspects associated with GQDs such as possible mechanisms, the impact of size, surface alteration, and doping with other elements, together with their technological and industrial applications have been envisaged. Till now, understanding simple photo luminance (PL) operations in GQDs is very critical as well as there are various methods derived from the optical properties of manufactured GQDs can differ. Lack of determining exact size and morphology is highly required without loss of their optical features. Finally, GQDs are promising candidates in the after-mentioned application fields.

ZnOHF/ZIF‐8 (Zeolitic Imidazolate Frameworks‐8) composite with a thickness of about 13.4 μm was coated on Zn–Cu–Ti alloy via hydrothermal route for the first time and its corrosion resistance performance was investigated in 3.5% NaCl solution. It is found that the Icorr of the composite‐coated alloy (7.03 × 10–4 A/cm2) is lower than that of alloy substrate (12.47 × 10–4 A/cm2). Meanwhile, the composite‐coated alloy shows a higher corrosion product resistance of 121.2 Ω cm2 in comparison with that of the alloy substrate (102.2 Ω cm2). Moreover, after 6 days of immersion, the composite‐coated alloy exhibits a lower corrosion layer thickness. Its coating and corrosion layer is only about 42.5 μm, but for the alloy substrate this value is 67 μm. This work confirms the ZnOHF/ZIF‐8 composite can be used as an effective anti‐corrosion coating for Zn alloy.
