Composite anti-fouling coatings and associated systems and methods are generally described. In some aspects, a system comprises a substrate, a composite coating disposed on at least a portion of the substrate, and a fluid comprising one or more foulants, where the composite coating is configured to be in physical contact with the fluid during use. The composite coating may comprise a first region comprising a first material and a second region comprising a second material that is different from the first material. According to some embodiments, a full- spectral Hamaker constant associated with the composite coating and the fluid (i.e., based on average optical properties of the first and second materials of the composite coating) is relatively low, and the van der Waals (vdW) force between the composite coating and the one or more foulants is, therefore, correspondingly low. Under some conditions (e.g., high temperature and/or high pressure conditions), intermolecular interactions between the composite coating and the one or more foulants may be dominated by the vdW force, and a relatively low vdW force may reduce the likelihood of the one or more foulants adhering to and/or otherwise being deposited on the composite coating. By selecting materials for the composite coating that result in a relatively low full- spectral Hamaker constant, fouling of the composite coating may thus be reduced or even eliminated. In some cases, two or more materials with optical properties (e.g., refractive indices, frequency-dependent dielectric response values) that, when averaged, are substantially similar to those of the fluid across a spectrum of frequencies or wavelengths may advantageously be associated with a relatively low full- spectral Hamaker constant.

The invention generally relates to a carbon-based boron removal medium with hydroxyl group and amine group, and in particular, to a method for forming the carbon-based boron removal medium. In various embodiments, nitrogen-doped (“N-doped”) graphene oxide is synthesized by a simple two-step process: (1) oxidation of graphite to graphene oxide, and (2) nitrogen-doping (“N-doping”) the graphene oxide to form the amine group. The resultant N-doped graphene oxide can efficiently remove boron from aqueous solutions. The invention also generally relates to a boron sensing medium and its use in conductometric measurement techniques to detect and measure the amount of boron present in aqueous solutions.

Abrégé

Composite anti-fouling coatings and associated systems and methods are generally described. In some aspects, a system comprises a substrate, a composite coating disposed on at least a portion of the substrate, and a fluid comprising one or more foulants, where the composite coating is configured to be in physical contact with the fluid during use. The composite coating may comprise a first region comprising a first material and a second region comprising a second material that is different from the first material. According to some embodiments, a full- spectral Hamaker constant associated with the composite coating and the fluid (i.e., based on average optical properties of the first and second materials of the composite coating) is relatively low, and the van der Waals (vdW) force between the composite coating and the one or more foulants is, therefore, correspondingly low. Under some conditions (e.g., high temperature and/or high pressure conditions), intermolecular interactions between the composite coating and the one or more foulants may be dominated by the vdW force, and a relatively low vdW force may reduce the likelihood of the one or more foulants adhering to and/or otherwise being deposited on the composite coating. By selecting materials for the composite coating that result in a relatively low full- spectral Hamaker constant, fouling of the composite coating may thus be reduced or even eliminated. In some cases, two or more materials with optical properties (e.g., refractive indices, frequency-dependent dielectric response values) that, when averaged, are substantially similar to those of the fluid across a spectrum of frequencies or wavelengths may advantageously be associated with a relatively low full- spectral Hamaker constant.
