Fabricating Superhydrophobic Protective Films with Enhanced Self‐Cleaning and Anti‐Corrosion Properties through Multiple Anodic Oxidations on Aluminum Alloys

“…Moreover, the corresponding detailed corrosion potential and corrosion current density values estimated from the Tafel polarization curves in Figure 6(A) are summarized in the Table 1. The corrosion resistance rate (CRR) corresponding to each current density is derived from the following equation: [27–30] $$$\vcenter{\openup.5em\halign{$\displaystyle{#}$\cr CRR(\char37 )=(J{_{1}}\hbox{-}J{_{2}})/J{_{1}}\times 100\mskip2mu \char37 \hfill\cr}}$$$ …”

Robust and Efficient Carbon-Based Planar Perovskite Solar Cells with a CsPbBr3–MoS2 Hybrid Absorber

“…Perovskites have attracted much attention and have been explored significantly due to their adjustable bandgap, long carrier diffusion length, high absorption coefficient, low exciton binding energy, etc. − Although the power conversion efficiency (PCE) of perovskite solar cells (PSCs) improved rapidly, organic–inorganic hybrid perovskite still suffers serious problems including poor stability against humid, oxygenous, and thermal work conditions. − In comparison with typical organic–inorganic hybrid perovskite, cesium lead bromide (CsPbBr 3 ) demonstrates excellent humid and thermal stabilities, low cost, and equipment restrictions. − Furthermore, carbon electrode-based PSCs (C-PSCs) with the absorber of CsPbBr 3 are encouraging for commercialization in consideration of their simple structure, high output voltage, and great stability. − Nevertheless, the PCE of CsPbBr 3 -based C-PSCs is still far from their theoretical efficiency due to the narrow optical response region and carrier loss at the interface between the absorber and the carbon electrode. − …”

“…The CsPbBr 3 film was fabricated by spin-coating aqueous solution of CsBr with a concentration of 250 mg/mL, and annealed at 250 °C for 5 min. 12 For comparison, CsPbBr 3 −MoS 2 hybrid film was fabricated by spincoating aqueous solution of CsBr (250 mg/mL) and MoS 2 (supernate taken from the centrifugation process with rotational speed of 8k, 12k, and 1:1 diluted solution, corresponding to the concentrations of 0.6, 0.4, and 0.2 mg/mL), and annealed at 250 °C for 5 min. Finally, the carbon electrode was fabricated on the perovskite layer by doctorblading the carbon paste and heating at 100 °C for 30 min.…”

Facile Fabrication of High‐White and Robust Superhydrophobic Ni/Al2O3 Composite Coating on Al Alloy

“…To obtain essential components in superhydrophobicity, namely, roughness and low adhesion to water, various surface modification technologies and methods have been developed, such as electrodeposition, electrospinning, spraying, chemical vapor deposition, and immersion coating. [24][25][26][27][28] Recently, it has been reported that Qi et al proposed an advanced method, they prepared micro/nanostructures and surface layers enriched with organic groups through nonsolvent-induced phase separation method for preparing superhydrophobic surfaces. [29] Wang et al compared different pretreatments for electrodepositing nickel-phosphorus coatings on the Al alloy surface and proposed an electrodeposition model using anodic oxidation pretreatment.…”
