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% 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: Some variations provide an anisotropic thermally conductive polymer composition comprising a plurality of polarizable, thermotropic main-chain liquid-crystal polymer molecules with crystalline domains. The liquid-crystal polymer molecules are in a nematic phase or a smectic phase, and at least 80% of the crystalline domains are aligned along a crystal axis. A method of making an anisotropic thermally conductive polymer composition comprises: synthesizing or obtaining a polymer containing polarizable domains; heating the polymer to form a polymer melt; cooling the polymer melt to form a thermotropic liquid-crystal polymer; exposing the thermotropic liquid-crystal polymer to an electrical field, thereby aligning the polarizable domains along a crystal axis; and recovering the thermotropic liquid-crystal polymer as an anisotropic thermally conductive polymer composition. The polymer composition may be formed into an object characterized by thermal conductivity along the minimum dimension that is at least three times greater than thermal conductivity along the maximum dimension.

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.
