“…In this composite designation 4.0 vol% of SSP is added and due to silane treatment it is distributed uniformly and enhances the bonding hence it does not allow to penetrate oxygen molecule throughout this and it's also oxygen level also reached maximum. [29,30] But SSP having more self-made natural carbonate phases such as CaCO 3 and MgCO 3 they do attract more with water molecules and marginally increased the overall water permeation percentage. [30][31][32] The formation of Ca(OH) 2 and Mg(OH) 2 tents to improve the water uptake behavior by providing large surface activation energy and restoring ability.…”

High toughness grape seed oil‐epoxy based composite coating material was prepared in this present study with sea urchin (Echinoidea) spike particle (SSP) for weather protection and insect repellent anti rusting coating applications. The main aim of this research was to study the effect of adding SSP along with grape seed oil in epoxy resin composite and their mechanical, thermal and barrier properties. The SSP used in this present study was prepared from marine waste dead sea‐urchin spikes using ball‐milling process. The prepared particles are then silane treated using aminosilane via acid hydrolysis. According to the results of the present study, the hardness values showed an increment of 7% for 4.0 vol% of SSP and 10 vol% of grape seed oil for composite designation EGS4. Similarly, the wear properties showed that the sp. wear rate and COF decreases up to 0.007 mm3/Nm and 0.51 for composite designation EGS4. However, for 10 vol% of grape seed oil and 0.5 vol% minimum mechanical properties were observed. The better thermal stability was observed for composite designation EGS4 whereas the barrier properties increased with 10 vol% of grape seed oil and 0.5 vol% of SSP. Nevertheless it is noted that the addition of SSP reduces the oxygen permeability and marginally increased the water permeability. These mechanically, thermally and barrier properties strengthened epoxy bio composite coating materials could be used in food packaging, medical and household product making applications.

“…Jeen-Robert et al [56] developed a superhydrophobic polymer nanocomposite (PNC) coating by mixing polyvinyl chloride, copper stearate, and ZnO NPs. The PNC coating was applied on Al-6061 alloy and the corrosive resistant behavior of the coating was examined.…”

“…The corrosion rate of coated substrate decreased from 23.75 mils per year (mpy) to 0.2253 mpy when compared with bare Al-6061. It was concluded that the developed super-hydrophobic polymer nanocomposite coating exhibited good anticorrosive property on Al-6061 alloy due to the super-hydrophobic activity of the nanocomposite [56]. Solano et al [16] also characterized and analyzed the ZnO and TiO 2 NPs when incorporated at different proportions into enamel paint.…”

Nanoparticles-modified paints have shown huge potentials in a broad range of functionalities like surface protection, antifouling, corrosion resistance, self-cleaning, slip resistance, abrasion resistance among others. Consequently, they have been deployed for several industrial applications including pipelines, buildings, automobiles, electronics, among others. To further enhance their functionalities, paint industries have expended huge resources on research and development of advanced paints that are compatible and appropriate for today's hostile environments. Studies have been conducted on the utilization of degradable biocides such as zinc oxide nanoparticles (ZnONPs), silver nanoparticles (AgNPs), copper nanoparticles (CuNPs), photocatalytic-active nano-titanium dioxide nanoparticles (TiO 2 NPs), and silica dioxide nanoparticles (SiO 2 NPs) as major additives in paints. These additives are designed to offer improved surface protection against microbial, physical, and chemical deteriorations as well as enhanced scratch resistance. However, the addition of nanoparticles to paints is not without its demerits. Nanoparticles can agglomerate within the paint matrix leading to poor surface protection. In addition, the health and safety concerns from human exposure to emissions of nanoparticles must be adequately addressed. A few reported studies on the toxicology of nanoparticles are either short-termed or having variant or inconclusive results. This paper reports a critical assessment of nanoparticles as additives in paints. Extensive characterization of nanoparticle-modified paints is reported while the implications on the environment are also explored. New directions, targeting enhanced functionalities and lower toxicity, are proposed.

“…59 The substrates often used are metals, textiles, fabrics, paper, wood surfaces and even stone monuments. [60][61][62][63][64][65][66][67][68] In all cases, the presence of the nanoparticles enhances the roughness in the nanoscale, which together with the usually inherent roughness in the micron scale can amplify the effects of a hydrophobic chemistry to superhydrophobicity and, even, water repellence. The type of nanoparticles utilized depends on the desired properties of the surface.…”
