“…Polymers are a vital part of the coatings industry. For example, polymer coatings are common on ship's hulls as marine fouling has been shown to reduce ships' efficiency by up to 86 %, which has huge financial and environmental implications [35,36]. Furthermore, the value of antimicrobial peptides for use in coatings within the medical industry was estimated at US $1.06 billion in 2015 [37,38].…”

The development of self-cleaning biomimetic surfaces has the potential to be of great benefit to human health, in addition to reducing the economic burden on industries worldwide. Consequently, this study developed a biomimetic wax surface using a moulding technique which emulated the topography of the self-cleaning Gladiolus hybridus (Gladioli) leaf. A comparison of topographies was performed for unmodified wax surfaces (control), biomimetic wax surfaces, and Gladioli leaves using optical profilometry and scanning electron microscopy. The results demonstrated that the biomimetic wax surface and Gladioli leaf had extremely similar surface roughness parameters, but the water contact angle of the Gladioli leaf was significantly higher than the replicated biomimetic surface. The self-cleaning properties of the biomimetic and control surfaces were compared by measuring their propensity to repel Escherichia coli and Listeria monocytogenes attachment, adhesion, and retention in mono- and co-culture conditions. When the bacterial assays were carried out in monoculture, the biomimetic surfaces retained fewer bacteria than the control surfaces. However, when using co-cultures of the bacterial species, only following the retention assays were the bacterial numbers reduced on the biomimetic surfaces. The results demonstrate that such surfaces may be effective in reducing biofouling if used in the appropriate medical, marine, and industrial scenarios. This study provides valuable insight into the antifouling physical and chemical control mechanisms found in plants, which are particularly appealing for engineering purposes.

“…The major drawback of aluminum alloys is the corrosion sensitivity in several environmental conditions, limiting its applicability for structural and functional applications, inducing relevant waste and serious contamination [ 5 , 6 , 7 , 8 ]. To avoid this issue and extend their application fields, many researchers proposed the use of a corrosion inhibitor, organic and inorganic coating, chromate-based coating, and anodized layers or polymer duplex coatings [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. However, these methods require complex processes, expensive equipment, and usually toxic chemical agents [ 17 ].…”

Effect of Chemical Surface Texturing on the Superhydrophobic Behavior of Micro–Nano-Roughened AA6082 Surfaces

Superhydrophobic surfaces on 6082 aluminum alloy substrates are tailored by low-cost chemical surface treatments coupled to a fluorine-free alkyl-silane coating deposition. In particular, three different surface treatments are investigated: boiling water, HF/HCl, and HNO3/HCl etching. The results show that the micro-nano structure and the wetting behavior are greatly influenced by the applied surface texturing treatment. After silanization, all the textured surfaces exhibit a superhydrophobic behavior. The highest water contact angle (WCA, ≈180°) is obtained by HF/HCl etching. Interestingly, the water sliding angle (WSA) is affected by the anisotropic surface characteristics. Indeed, for the HF/HCl and the HNO3/HCl samples, the WSA in the longitudinal direction is lower than the transversal one, which slightly affects the self-cleaning capacity. The results point out that the superhydrophobic behavior of the aluminum alloys surface can be easily tailored by performing a two-step procedure: (i) roughening treatment and (ii) surface chemical silanization. Considering these promising results, the aim of further studies will be to improve the knowledge and optimize the process parameters in order to tailor a superhydrophobic surface with an effective performance in terms of stability and durability.

“…Nevertheless, increasing social awareness within the ranks of consumers has propelled investment in corporately socially responsibility toward manufacturing of ecobenign sustainable products with minimized carbon footprints. On the other hand, inclusion of nanoparticles likes graphene nanoplatelets, and so on, in polymeric matrices along with fibrous entities have derived polymer nano-biocomposites with exceptional properties with potential of applications in areas where heat dissipation, thermal conductivity, and fire suppression are essential like the automobile, aerospace, maritime, military, oil and gas, and so on (Butt et al, 2016;Idumah et al, 2014;Idumah, 2020aIdumah, , 2020bIdumah, , 2020cIdumah & Hassan, 2016;Idumah, Hassan, & Bourbigot, 2018;Idumah & Nwachukwu, 2013a, 2013bIdumah, Nwachukwu, Akubue, Anyigor, 2013;Idumah, Nwuzor, et al, 2020;Idumah, Hassan, et al, 2019;, 2016a, 2016b, 2016c, 2016d, 2016e, 2017Idumah, Ogbu et al, 2019;Idumah, Hassan, Ogbu, Ndem, & Nwuzor, 2018;Idumah, Hassan, Ogbu, Ndem, Oti, et al, 2018;Idumah, Obele, Ezeani, & Hassan, 2020;Iliew et al, 2004;Kanagaraj et al, 2008;Kong et al, 2015;Leire & Thidell, 2005;Schurig et al, 2006;Smith et al, 2004;Upadhyay et al, 2015;You et al, 2015).

In recent years, nanotechnology (NT) has proved to be an interdisciplinary research field, and has enlarged its scope of applications in versatile areas of human endeavor. The quests for enhanced multifunctionality in engineering, industrial, technical, and medical textiles have instigated nanotechnological evolution in textile materials. The inclusions of novel technologies such as photonic crystals, plasmonics, luminescence, architectural colorants, holography, LED displays, and metamaterials within textile materials have inculcated multifunctionalities to these materials. NT advancements in textiles through nanoparticles (NPs), and sensor integration within textile materials have enhanced physicochemical behaviors of textiles such as self-cleaning, UV-protection, flame resistance, and antimicrobial, among so on, versatile sensory capabilities, robotics, electrical conductivity, flexibility and comfort, thereby availing it for health, medical, sporting, advanced engineering, pharmaceuticals, aerospace, military, automobile, food and agricultural applications, and more. Fibers inculcated with metallic nanoparticles, such as copper and silver NPs have demonstrated antiviral, and antimicrobial attributes. In this era of COVID-19, NT has enhanced personal protective equipments and fortified antiviral behavior. Therefore, this article elucidates novel nanotechnological advancements in textiles, novel applications, and fight against COVID-19 pandemic.
