Fluoropolymer: A Review on Its Emulsion Preparation and Wettability to Solid-Liquid Interface

Abstract

In the preparation of a superamphiphobic surface, the most basic method is to reduce the surface free energy of the interface. The C—F bond has a very low surface free energy, which can significantly change the wettability of the solid–liquid interface and make it a hydrophobic or oleophobic, or even superamphiphobic surface. Based on the analysis of a large number of research articles, the preparation and application progress in fluoropolymer emulsion were summarized. After that, some corresponding thoughts were put forward combined with our professional characteristics. According to recent research, the status of the fluoropolymer emulsion preparation system was analyzed. In addition, all related aspects of fluoropolymer emulsion were systematically classified in varying degrees. Furthermore, the interaction between fluoropolymer structure and properties, especially the interaction with nanomaterials, was also explored. The aim of this review is to try to attract more scholars’ attention to fluorocarbon interfacial materials. It is expected that it will make a certain theoretical and practical significance in the preparation and application of fluoropolymer.

Multilevel Information Encryption Based on Thermochromic Perovskite Microcapsules via Orthogonal Photic and Thermal Stimuli Responses

“…A series of fluorocarbon surfactants with different carbon chain structures are then designed, and the FLB values are derived to assess the stabilization effect (Table S1). − The surfactants with branched chains such as pincer structures, which can firmly attach to the interface, produce better emulsification and stabilizing effects. Accordingly, heptadecafluorodecyl tris­(pentan-3-yloxy) silane (HFPS) (FLB = 9.40) is synthesized (Scheme S1 and details in Supporting Information), and the chemical structure is determined by NMR (Figures S2 and S3).…”

Localized Surface Plasmon Resonance Sensing and its Interplay with Fluidics

“…LSPR sensors can be employed in examining the interfacial phenomena at both solid–liquid and liquid–liquid interfaces. − This sensitivity stems from LSPR’s ability to detect changes in the refractive index of nanostructures situated within distances of 5–10 nm from the surface. This specific range aligns with the realm where interfacial effects hold significant sway, rendering the LSPR highly relevant for exploring a wide array of applications.…”

Polymerization-Induced Hierarchical Hybrid Particles from Siloxane Emulsification Endowing Polyurethane Composite Coating with Superhydrophobicity, Thermal Insulation, and Fluorescence

“…The superhydrophobic coating is mainly determined by the rough structure and surface chemical compositions. − The incorporation of micron/nanoparticles is commonly used to enhance the roughness of the coating due to the particles’ inherent large specific surface area, and fluorocarbons are the most representative low-surface-energy materials. − Thus, the methods of constructing superhydrophobic coatings based on fluorocarbon-modified particles have been extensively investigated. − Jiao et al created superamphiphobic coatings by spray-coating the suspension of perfluoro-decyltrichlorosilane-modified silica nanoparticle powders and ceramic binders, which exhibited excellent liquid repellency against several low-surface-tension liquids. In addition, it is necessary to find an eco-friendly substrate with good adhesion and film-forming properties that can combine strongly with particles.…”
