“…PEsA polyols have been developed by the reaction of NEVO fatty amides with diacids to improve the properties of coatings, such as corrosion resistance, thermal properties, and physicomechanical properties [ 62 ]. Gite et al prepared AO-based PEsA polyols using different diacids and utilized them for the development of anticorrosive and antimicrobial PU coatings [ 26 , 103 , 104 ]. LO-based PEsA polyols have been developed by the reaction of LO fatty amides with ethylenediaminetetraacetic acid (EDTA) [ 62 ].…”

“…Various nanofillers, such as fumed silica, TiO 2 , ZnO, and Fe 2 O 3 NPs, have been reported in NEVO-based polyols and PUs [ 112 , 118 , 149 , 150 , 154 ]. PU with silver (Ag)-doped hydroxyapatite (HAP) NPs and the PEsA polyol were prepared from AO and ricinoleic acid, exhibiting anticorrosion characteristics ( Table 4 , Figure 11 ) [ 104 ]. The improved anticorrosion characteristics were attributed to the nonporous, hydrophobic nature of the coating and the presence of hydrolytically stable urethane bonds, which provided better adhesion of the coatings to the substrate.…”

This review describes the preparation of nonedible vegetable oil (NEVO)-based polyols and their application in anticorrosive and antimicrobial polyurethane (PU) coatings. PUs are a class of versatile polymers made up of polyols and isocyanates. Renewable vegetable oils are promising resources for the development of ecofriendly polyols and the corresponding PUs. Researchers are interested in NEVOs because they provide an alternative to critical global food issues. The cultivation of plant resources for NEVOs can also be popularized globally by utilizing marginal land or wastelands. Polyols can be prepared from NEVOs following different conversion routes, including esterification, etherification, amidation, ozonolysis, hydrogenation, hydroformylation, thio-ene, acrylation, and epoxidation. These polyols can be incorporated into the PU network for coating applications. Metal surface corrosion and microbial growth are severe problems that cause enormous economic losses annually. These problems can be overcome by NEVO-based PU coatings, incorporating functional ingredients such as corrosion inhibitors and antimicrobial agents. The preferred coatings have great potential in high performance, smart, and functional applications, including in biomedical fields, to cope with emerging threats such as COVID-19.

“…Thus, they need to be replaced with green, biobased renewable materials that have a significantly lower ecological impact [ 2 ]. While chitosan has been a long-standing green biobased antimicrobial material [ 13 ], many other materials such as biobased polyurethane and Ag nanocomposite [ 17 , 5 ], chitosan bionanocomposites [ 23 ], Ag nanoparticles from orange waste [ 4 ], nanocellulose [ 14 ] have been proposed in the recent past in this regard.…”

“…These AgNP loaded silk fibres were able to inhibit >90% P. aeruginosa and S. aureus . Biobased polyurethane derived from renewable materials like algae oil and ricinoleic acid silver doped chicken egg-shell nanoparticles (AgNP) was found to be an excellent antimicrobial surfactant against gram-negative and gram-positive bacteria such as E. coli and S. aureus [ 5 ]. Preliminary evaluations by [ 11 ] on a modified coating using quaternary ammonium coating are highly effective against human coronavirus (HCoV) 229E, with remediation rate of >90% in 10 minutes and by > 99.9% after 2h contact.…”

There has been a growing concern for safety and precautions in the wake of coronavirus SARS-CoV2 pandemic also dubbed as COVID-19, which has caused a major impact at a global scale. This has resulted in many industries accelerating at fast pace new biosafety technologies and improving the already existing ones to deal with this highly contagious virus. Most governments across the globe are also mandating policies focusing on increased biosafety to prevent further spread of the virus and protect key workers such as healthcare agents, store employees and police. The COVID-19 pandemic has exposed huge gaps in the healthcare industry that include lack of effective vaccines and medicines, testing of infection, real-time monitoring of the spread of the virus, inadequate protective equipment, and scarcity of protective and intensive care of patients. Some of these may be attributed to a lack of focused research in biosafety materials. As a consequence of the pandemic, a significant body of research activities has therefore focused on biosafety materials that possess unique properties needed for biosafety applications. This graphical review aims to provide a perspective on the usage of bio-based materials to handle the imposing challenges in biosafety. This review investigates existing developments in bio-based antimicrobial encapsulations as an effective measure to deter the growth of COVID-19 virus on surfaces and minimize its spread through surface contact. This will help researchers develop further strategies in material science to focus on contagious pathogens in the future.

The present investigation demonstrates renewable cardanol based polyol for the formulation of nanocomposite polyurethane (PU) coatings. The functional and structural features of cardanol polyol and nanoparticles were studied by FT-IR and 1H NMR spectroscopic techniques. The magnetic hydroxyapatite nanoparticles (MHAP) were dispersed in PU formulations to develop nanocomposite anticorrosive coatings. The amount of MHAP in PU formulations was varied from 1-5%, increase the percentage of MHAP increases the anticorrosive performance as examined by immersion and electrochemical methods. The nanocomposite PU coatings shows good coating properties viz., gloss, pencil hardness, flexibility, cross-cut adhesion and chemical resistance. Additionally, the coatings also studied for surface morphology, wetting, and thermal properties by scanning electron microscope (SEM), contact angle, and thermogravimetric analysis (TGA), respectively. The hydrophobic nature of PU coatings increased by addition of MHAP and optimum result (1050) was observed in 3% loading. The developed coatings revealed hydrophobic nature with excellent anticorrosive performance.
