“…The WCA data showed that the surface of coating was not affected obviously after 3 h of the dripping process. These results proved that the coating had good self-cleaning and adhesion properties when used on many different substrates, especially for hard materials, such as those which may be used in making radar-absorbing material and stealth aircraft material …”

Converting waste wheat straw to conductive superhydrophobic nanocarbon materials is inspired by mosquito's compound eyes, and a one step pyrolysis process is used for controllable construction of micro/nanohierarchical structures. Their structures and hydrophobicity can be tuned efficiently by the annealing temperature. Scanning electron microscopy, elemental analysis, X-ray diffraction, laser Raman, Fourier transform infrared, and photoelectron spectroscopy analyses were used to reveal the structure of electrical conductive carbon materials (ECMs) and a possible mechanism of the nanostructures formation. These results indicate that there are big differences between the surface and the inner structure for the nanocarbon materials, and the releasing rates of a multicomponent gas at different annealing temperatures by further decomposition of waste wheat straw should be pivotal to the formation of nanostructures. There is also cause for superhydrophobicity and electroconductivity for the ECM-800. Considering the potential use of the novel ECM-800, a low-cost, green, sustainable, conductive, and superhydrophobic coating strategy was developed by dip-coating of the different substrates with a ECM-800/PDMS mixture, followed by thermal curing. The water contact angle of the prepared ECM-800/ PDMS coating is greater than 160°, while the sliding angle is less than 5°, showing excellent superhydrophobicity as well as good mechanical robustness and water-repellency in the artificial rain tests simultaneously. In addition, a robust ECM-800 enables resistance to a variety of harsh environments, such as an ability to resist heat and UV aging as well as sustaining exposure to strong acid/alkaline corrosion. Moreover, this work should be conducive to the controllable construction of conductive superhydrophobic nanocarbon materials with well-defined structure, and open up a convenient sustainable way for disposal of waste biomass for production of value-added materials.

“…Some resins are affected by prolonged water contact and freeze/thaw action can be damaging to the composite structure. The right paint system will provide a moisture barrier and protect the composite from damaging fluids such as hydraulic fluid and fuel [6]. Moreover, for CFRP composite, painting is often required to protect the surface from long-term UV irradiation that may decompose the polymeric matrix [7], resulting in exposure of carbon fibres which contributes to the failure of the composite.…”

Enhancing Coating Adhesion on Fibre-Reinforced Composite by Femtosecond Laser Texturing

2023

Carbon fibre-reinforced polymers (CFRP), thanks to their properties such as lightness, resistance to corrosion and fatigue, are emerging composite materials in the aeronautic fields, guaranteeing to reduce weight and costs by maintaining high performances in terms of strength and security. For preventing fluid damage and freezing, in aeronautic applications, CFRP parts need to be coated by painting. However, the paint/coating adhesion on CFRP composites is generally poor and affected by surface conditions. In this work, femtosecond laser texturing was investigated as an approach to improve adhesion of superhydrophobic coatings (SHC) to CFRP substrates. The laser textured surfaces show, after coating, a more lasting superhydrophobic behaviour compared to the as received sample, even after several cleaning cycles, demonstrating that the laser pre-treatment is a reliable and green method to enhance the adhesion of the SHC to the composite substrate.
