“…This technique aims to improve the performance of a component by adding a functionalised coating to the surface ( Ref 15). Anti-corrosion (Ref [16][17][18][19], low friction and wear resistance (Ref [20][21][22][23], chemical and weathering resistance (Ref 24,25), and antifouling (Ref 26,27) represent some of the applications of the thermally sprayed coatings. In particular, flame spraying represents one of the thermal spray techniques used for the production of polymer coatings.…”

The present work investigates the effect of different process parameters on the production of low-density polyethylene (LDPE) coatings by flame spray technology. Previously, flame spraying of polymers has been successfully performed to obtain durable icephobic coatings, providing an interesting solution for applications facing icing problems, e.g. in marine, aviation, energy, and transportation industry. However, the fine tailoring of the process parameters represents a necessary strategy for optimising the coating production due to the unique thermal properties of each polymer. For this purpose, we vary the heat input of the process during flame spraying of the coating, by changing the transverse speed and the spraying distance. The results show that the variation in the process parameters strongly influenced the quality of the polymer coating, including its areal roughness, thickness, chemical composition, thermal stability, and degree of crystallinity. Furthermore, we demonstrate that these properties significantly affect the icephobic behaviour of the surface within the spray window of the chosen parameters. In conclusion, the relationship between the thermal degradation of the polymer and the icephobicity of the surface was defined. This highlights the importance of process parameter optimisation in order to achieve the desired icephobic performance of the LPDE coatings.

“…In this study, surface with 0.3% AgNPs showed the highest antibacterial potential, with the amount of AgNPs in the coating being much lower than previous studies. 19 The antibacterial rate of the coatings is shown in Table 2. The antibacterial rate of 0.05% AgNPs against S. aureus was 99.43%, and the antibacterial rate against E. coli reached 99.80%.…”

“…18 Secondly, the synthetic AgNPs have poor compatibility with the polymer resin, which will decrease the uniformity of and thus also inuencing its antifouling efficiency. 19 Lastly, the AgNPs-based antifouling coating prepared by two-step method has short-term efficiency because of the rapid consumption of Ag + . 20 Developing a simple, environmentally friendly, highly efficient, and long-lasting marine antifouling coating is still a signicant challenge.…”

Biofouling is very harmful in diverse industries. Copper nanoparticles (Cu NPs) possess excellent antifouling performances. In this study, in situ generation of Cu NPs on dopamine modified 304 stainless steel (SS) surface layer‐by‐layer in weak alkaline solution was reported. Field emission scanning electron microscope equipped with energy dispersive spectrometer, atomic force microscope, and X‐ray photoelectron spectroscopy were utilized to analyze the surface morphology and chemical composition of the modified SS. The results demonstrated that the surface of SS was coated with polydopamine (PDA) and Cu NPs successfully. The robustness assay of the Cu NPs surface demonstrated that most Cu NPs had bound on the surface of the stainless steel firmly. Antimicrobial assays showed that modified surface possessed the ability of resistance of Escherichia coli and Staphylococcus aureus to an effectiveness of 92.1% and 80.4%, respectively. The presence of copper offers the coatings' excellent capability to inhibit effectively the adhesion of marine diatom Phaeodactylum tricornutum to an effectiveness of 98.15%. This strategy exhibited a realistic paradigm for further improving the antifouling performances of hull surfaces.
