“…Results indicated that both of T 5% and T 50% decline as content of fluorine increase from FPU‐1 to FPU‐5. It accords with the report of literature . The degradation of the urethane component begins first from its hard segment (T 1 ) and the soft segment starts to decompose at a temperature of 350°C or above.…”

A novel fluorinated chain extender, (1-(ethyl(2-hydroxyethyl)amino)-3- ((3,3,4,4,5,5,6, 6,7,7,8,8,8-tridecafluorooctyl)oxy)propan-2-ol) (FPO), was synthesized and characterized by nuclear magnetic resonance (NMR), Fourier transform infrared (FTIR), and elemental analysis. Poly (ether urethane)s containing various amounts of the chain extender with fluorinated side chains (FPUs) were prepared by isophorone diisocyanate (IPDI), polytetra-methylene-ether-glycol (PTMG), 3-aminopropyltriethoxysilane (KH-550), and 1,4-butandiol (BDO). Films of FPUs were investigated by water absorption, contact angle, pencil hardness, adhesive force, and thermal analysis. Coating FPUs on micro-nano concave-convex structure plate realizes superhydrophobic performance.Scanning electron microscope (SEM) and atomic force microscopy (AFM) demonstrated that there is a lot of irregular concave-convex structure, which forms a typical air cushion model. X-ray photoelectron spectroscopy (XPS) analysis showed that surface fluorine content is 165% more than that of film average fluorine content. The superhydrophobic plate with 10% or higher F-containing FPUs coating is of outstanding chemical corrosion resistance, excellent solvent resistance, and wear resistance.

“…Generally, to introduce organofluorine units into polyurethane, the fluorine unit was embedded into the backbone of polyurethane chain through a covalent bon [ 12 , 13 , 14 ]. Wen [ 15 ] prepared a fluoro alcohol-terminated isocyanate trimer by 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluoro-1-octanol and hexamethylene diisocyanate trimer, and then fabricated a series of fluorine-containing water-based polyurethanes ( Figure 1 ). By controlling the fluorine content, the PU was endowed with low surface free energy and great wetting ability.…”

Over last few years, polyurethane (PU) has been applied in a number of areas because of its remarkable features, such as excellent mechanical strength, good abrasion resistance, toughness, low temperature flexibility, etc. More specifically, PU can be easily “tailor made” to meet specific demands. This structure–property relationship endows great potential for use in wider applications. With the improvement of living standards, ordinary polyurethane products cannot meet people’s growing needs for comfort, quality, and novelty. This has recently drawn enormous commercial and academic attention to the development of functional polyurethane. Among the major applications, PU is one of the prominent retanning agents and coating materials in leather manufacturing. This review gives a summary of academic study in the field of functional PU as well as its recent application in leather manufacture.

“…As a water-based locomotive topcoat, WPU shows excellent mechanical properties, good compatibility, good moldability, and easy modification to meet the performance and application requirements [6,7]. WPU can be widely used in coatings, adhesives, wood processing, automotive manufacturing, medicine, and other fields [8][9][10]. In recent years, WPU modification and long-term reliability evaluation have attracted much attention.…”

This paper reports the effects of different formulas on the performance of waterborne polyurethane (WPU), including two-component WPU and curing agent, wetting dispersant, defoaming agent, and wetting agent. The optimization of rheological additives selection, through the optimization of coating physical properties and chemical properties, can make the film show uniform color and appearance without pinholes, bubbles, or wrinkles, and have a long probation period. Through the analysis of performance after a 1000-h quick ultraviolet (QUV) aging test, the light reduction rate is 23.19%, and the color difference is 1.9. As can be seen from the scanning electron microscope (SEM) image and the three-dimensional stereomicroscope, the film shows relatively uniform dispersion, good compactness, and smooth surface. The two-component WPU topcoat is found to have high gloss 87.1 (60°) and high weather resistance, which provides a positive indication for the modulation and production of waterborne locomotive paint.
