(Co)polymers of Chlorotrifluoroethylene: Synthesis, Properties, and Applications http://pubs.acs.org/doi/abs/10.1021/cr2002933 由于F原子比較小以及強的負電性,C-F鍵使得含氟聚合物具有了很多優(yōu)于其他聚合物材料的特性,使其在很多領(lǐng)域具有很好的應(yīng)用前景 Fluorinated polymers are niche macromolecules that attract much interest because of the versatility of a wide range of applications. Their use ranges from thermoplastics, elastomers, and plastomers to thermoplastic elastomers as well as from semicrystalline to fully amorphous. Furthermore, largely due to the properties of the fluorine element (strong electronegativity, low polarizability, and small van der Waals radius (1.32 Å ) and to the strong C−F bonds (485 kJ mol−1), they exhibit unique and remarkable properties. Hence, fluoropolymers with a high fluorine content exhibit exceptional properties. These include high chemical, thermal, aging, and weather resistance as well as outstanding inertness to hydrocarbons, solvents, acids, and bases. Other highly desirable properties include low dielectric constant, low surface energy (water and oil repellency), low flammability, low refractive index, and low moisture absorption. Furthermore, the high strength of the C−F bond in these polymers has a critical impact on their great resistance to both hydrolytic and oxidation stability.該綜述在第一部分總結(jié)了CTFE的不同合成方法;第二部分綜述了CTFE的二元以及三元共聚合成;第三部分也就是最主要的部分各種不同的CTFE二元共聚物的自由基聚合;第四部分講了如何設(shè)計和改性CTFE的二元共聚物;最后一部分給出了CTFE-based 聚合物的應(yīng)用。 屏幕快照 2014-02-23 23.39.12.png |
