Abstract: Aspects of the present disclosure relate to Schiff base oligomers and uses thereof. In at least one aspect, an oligomer is represented by Formula (IV) wherein each instance of R9 is independently selected from the group consisting of alkyl, cycloalkyl, aryl, heteroaryl, and ether. Each instance of R28 and R29 of Formula (IV) is independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, and aryl. Each instance of R33 of Formula (IV) is independently selected from the group consisting of alkyl, cycloalkyl, aryl, heterocyclyl, and a bond. Each instance of R41 of Formula (IV) is independently —NH— or a bond and each instance of R40 is independently —NH— or —NH—NH—. Each instance of R42 of Formula (IV) is independently —NH— or a bond and each instance of R43 is independently —NH— or —NH—NH—.

Abstract: A corrosion inhibitor coating composition includes a polymerized thiosemicarbazone, and a thiirane crosslinker, where the thiirane crosslinker is a difunctional molecule. The corrosion inhibitor coating composition can include where the thiirane crosslinker may include an aliphatic thiirane, a tri-functional thiirane, a bisphenol thiirane, or a combination thereof. The corrosion inhibitor coating composition can be metal-free and catalyst-free. An article utilizing and a method of preparing a corrosion inhibitor coating composition is also disclosed, which can include adding a thiourea to a difunctional epoxy terminated molecule in solution in the presence of a catalyst, converting the difunctional epoxy terminated molecule to a thiirane terminated difunctional molecule, and purifying the thiirane terminated difunctional molecule to produce a thiirane.

Abstract: Aspects of the present disclosure relate to Schiff base oligomers and uses thereof. In at least one aspect, an oligomer is represented by Formula (I) wherein each instance of R4, R5, R6, R7, R8, R10, R11, R12, R13, and R14 is independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, alkoxyl, aryloxyl, ether, and heterocyclyl. Each instance of R9 of Formula (I) is independently selected from the group consisting of alkyl, cycloalkyl, aryl, heterocyclyl, and ether. Each instance of R28 and R29 of Formula (I) is independently selected from the group consisting of hydrogen, alkyl, and aryl. Each instance of R33 of Formula (I) is independently selected from the group consisting of alkyl, cycloalkyl, aryl, heterocyclyl, and a bond. Each instance of R41 of Formula (I) is independently —NH— or a bond and each instance of R40 is independently —NH— or —NH—NH—.

Abstract: Coating compositions that may be used in combination with UV light for sterilization include a polyurethane component and nanoparticles having an average particle size of from about 30 nm to about 400 nm. The nanoparticles absorb light having a wavelength of from about 100 nm to about 290 nm, and are present in an amount of less than about 25 weight percent of total solids in the coating composition.
