Abstract: An antimicrobial coating is disclosed that provides fast transport rates of biocides for better effectiveness to deactivate SARS-CoV-2 and other viruses or bacteria on common surfaces. Some variations provide an antimicrobial structure comprising: a solid structural phase comprising a solid structural material; a continuous transport phase that is interspersed within the solid structural phase, wherein the continuous transport phase comprises a solid transport material; and an antimicrobial agent contained within the continuous transport phase, wherein the solid structural phase and the continuous transport phase are separated by an average phase-separation length from about 100 nanometers to about 500 microns. The antimicrobial structure is capable of destroying at least 99.99 wt % of bacteria and/or viruses in 10 minutes of contact. Many options are disclosed for suitable materials to form the solid structural phase, the continuous transport phase, and the antimicrobial agent.

Abstract: The disclosed technology provides a vitrimeric poly(diketoenamine) network comprising: a plurality of multifunctional triketone dimers; a plurality of multifunctional amine species containing primary or secondary amine groups, but no tertiary amine groups; and optionally, one or more amine-reactive groups. The disclosed technology also provides a method of making a vitrimeric polymer network, comprising: obtaining multifunctional triketone dimers; obtaining a multifunctional imine compound, with imine groups blocking amine groups; mixing the multifunctional triketone dimers with the multifunctional imine compound, thereby forming a polymer precursor mixture; applying the polymer precursor mixture onto a substrate; and allowing the multifunctional imine compound to undergo hydrolysis with water, unblocking the amine functional groups and generating a multifunctional amine compound. The multifunctional amine compound reacts with the multifunctional triketone dimers to form a vitrimeric polymer network. The vitrimeric polymer network may be depolymerized back to monomers, which may be repolymerized in a closed-loop system.

Abstract: This disclosure provides corrosion-resistant coatings that significantly improve corrosion resistance compared to the prior art. The corrosion protection system senses gradients in electrical potential, pH, and metal ion concentration, and then automatically halts corrosion. Some variations provide a gradient-responsive corrosion-resistant coating comprising: a first layer comprising a transition metal oxide and mobile cations; a second layer comprising a biphasic polymer, wherein the biphasic polymer contains ionic groups, wherein the biphasic polymer comprises a discrete phase and a continuous transport phase, wherein the continuous transport phase is capable of delivering oligomers in response to corrosion byproducts, and wherein the oligomers are ionically crosslinkable with metal cations from a base metal substrate. Other variations provide a corrosion protection system comprising: a base metallic layer; a metal oxide layer comprising a transition metal oxide and mobile cations; a polymer layer comprising a biphasic polymer; and a sealing layer disposed on the polymer layer.
