“…Because both hydrophilic and hydrophobic surfaces of materials have important industrial applications, their interactions with liquids have been studied. [1][2][3][4] Especially, surfaces decorated with carbon-based thin structures, including graphene and carbon nanotube sheet, show unique properties, such as fast water transport in graphene nano channels 5) and transparent hydrophilicity through graphene. 6) Moreover, triboelectrification at the solid-liquid interface still remains to be fully understood.…”

The interactions between a solid and a liquid at their interface often produces exotic effects that could be used in energy-related applications. To this end, the understanding of which properties controls the zeta potentials at the interface promises to advance the application of these effects. In this study, we fabricated fluorocarbon films by plasma-enhanced chemical vapor deposition to investigate the interaction of the film with aqueous solution. We found that the properties of the films can be controlled by the deposition pressure and the zeta potential correlates with the bonding states within the films. The control of the interfacial potential between the solid material and the aqueous solution can be a factor for maximizing energy output and optimizing device design.

Membrane-based technology has been extensively applied in seawater desalination and wastewater reclamation, but its sustainable applications are limited by the inevitable membrane fouling. Modifying membranes is a widely used approach to mitigate biofouling in membrane preparation processes. However, high costs and complexity of the modification limit the practical applications of this approach. In this work, a biocompatible and robust coating strategy was adopted to mitigate fouling caused by biomacromolecules and microbes in an environmentally friendly way. The phase-transited bovine serum albumin (PTB) coating was triggered by soaking membranes in the mixture of the protein and a reductant. The coating preserved the porous structures of membranes and also maintained the water flux of the microfiltration membrane in dead-end filtration tests. Moreover, the PTB-coated membranes exhibited high antifouling properties toward both biomacromolecules and microbes. In particular, the most significant improvement against membrane fouling was observed for sodium alginate, followed by bovine serum albumin and humic acid. Additionally, the membrane fouling caused by Sphingomonas wittichii and Aeromonas hydrophila was also efficiently mitigated. These improved antifouling performances were found to be attributed to the negatively charged membrane surface after PTB coating. This work provides a feasible and environmentally friendly approach to modify membranes to mitigate biofouling without compromising its original porous structure and water flux.
