“…Some coatings show excellent mechanical robustness, but their preparation process is more complicated 49,50 and some of them can only be applied to specific substrates. 16,51 Compared with these previous reports, the sandpaper abrasion robustness of the sample (SHC-0.05AP-DE) in this work is higher than most of the other superhydrophobic coatings. Furthermore, the one-step painting fabrication method of the coating is relatively simple and the coating can be coated onto various substrates, such as glass, metal and plastic.…”

Facile fabrication of superhydrophobic coatings with excellent mechanical robustness is highly desired in practical application. Herein, a convenient and effective strategy for one-step fabrication of robust volumetric superhydrophobic coating was developed containing aminosilane-functionalized cylindrical diatomaceous earth (DE) particles and a polyurethane (PU) resin. Due to the strong chemical cross-linking between the amino groups and the isocyanates, the superhydrophobic DE particles were strongly anchored to the PU resin, thus improving the wear resistance of the coating. The coating could withstand 20 m sandpaper abrasion under a constant pressure of 2.6 kPa. The wear resistance of the coating improved nearly 471% compared with the superhydrophobic DE/PU composite coating prepared by physical-blending. Moreover, the coating also demonstrated great self-cleaning performance, excellent chemical stability and underwater durability. Additionally, the as-prepared coating could be easily applied to various substrates and exhibited high rigidity (3H-4H), good adhesion (4B-5B), and great flexibility (impact resistance of 1 KgÁm).

“…The polydimethylsiloxane loaded with fluoroalkyl silane (FAS) functionalized with cerium dioxide (CeO 2 ) was applied by spray on the supports; the contact angle with water was 161 ± 2°, indicating excellent hydrophobic behavior. The super hydrophobicity is due to its surface consisting of a multi-level structure in micro and nano scale [ 25 ]. The same authors (An et al) also point out that the air pockets formed in the grooves by the micro-nano structure help to reduce the contact area of the water drop on the surface, thus improving the anti-wetting properties.…”

Mechanical Properties of Protective Coatings against Marine Fouling: A Review

2021

The accumulation of marine organisms on ship hulls, such as microorganisms, barnacles, and seaweeds, represents a global problem for maritime industries, with both economic and environmental costs. The use of biocide-containing paints poses a serious threat to marine ecosystems, affecting both target and non-target organisms driving science and technology towards non-biocidal solutions based on physico-chemical and materials properties of coatings. The review reports recent development of hydrophobic protective coatings in terms of mechanical properties, correlated with the wet ability features. The attention is focused mainly on coatings based on siloxane and epoxy resin due to the wide application fields of such systems in the marine industry. Polyurethane and other systems have been considered as well. These coatings for anti-fouling applications needs to be both long-term mechanically stable, perfectly adherent with the metallic/composite substrate, and capable to detach/destroy the fouling organism. Prospects should focus on developing even “greener” antifouling coatings solutions. These coatings should also be readily addressable to industrial scale-up for large-scale product distribution, possibly at a reasonable cost.

“…Development of such applications requires the use of a convenient matrix for efficient incorporation of the nanoparticles, to enhance the performance, avoid the cluster growth and aggregation and improve the handling and recovery of the nanoparticles. Up to now, CeO 2 particles were incorporated in various polymeric templates such as poly(meth)acrylates [ 6 , 7 , 8 ] polyurethanes [ 9 , 10 ], polyimides [ 11 ], polyamides [ 12 ] or polydimethylsiloxanes [ 13 ]. Among the plethora of polymers, one of the best candidates to immobilize CeO 2 nanoparticles (NPs), which fits both environmental and economic issues is represented by cellulose [ 14 , 15 ].…”

One of the major issues faced when constructing various materials incorporating inorganic nanoparticles (NPs) is aggregation leading to loss of their final activity. In our work, cellulose acetate (CA) has been used to serve as matrix for the synthesis of UV-shielding and transparent films containing various amounts (1–5 wt.%) of cerium oxide (CeO2) NPs. In order to attain an improved dispersion and a better connectivity between NPs and the cellulose matrix, the surface of CeO2 NPs have been previously functionalized by the reaction with 3-aminopropyl(diethoxy)methylsilane (APDMS). The uniform dispersion of the NPs in the homogeneous thin films has been evidenced by using Transmission Electron Microscopy (TEM) and Fourier Transformation Infrared Spectroscopy (FTIR) characterization. The investigation of the optical properties for the hybrid films through UV-Vis spectroscopy revealed that the presence of CeO2 NPs in the CA matrix determined the appearance of strong UV absorption bands in the region 312–317 nm, which supports their use as efficient UV absorbers. This study has shown that UV shielding ability of the nanocomposites can be easily tuned by adjusting the numberof inorganic NPs in the CA template.
