  A method of making a functionalized fluorinated monomer for use in making oligomers and polymers that can be used to improve surface properties of polymer-derived systems, such as coatings. The method of making a functionalized fluorinated monomer includes reacting at least one fluorinated nucleophilic reactant, such as a fluorinated alcohol, with at least one compound containing at least one epoxide group. Other methods include reaction of a fluorinated alcohol with a cyclic carboxylic anhydride. In another embodiment, a method includes reacting a fluorinated mesylate, tosylate or triflate with an amine, alkoxide or phenoxide. In other embodiments, the method includes reacting a fluorinated alcohol with an alkyl halide, or reacting a fluorinated alkyl halide with an amine. The functionalized fluorinated monomers may be used as intermediates and reacted to modify the functional groups thereon. Further, the functionalized fluorinated monomers may be reacted to form polymers or oligomers, or with polymers or oligomers having functional groups to modify the polymer or oligomer through the functional group thereon,

  一种制备用于制备寡聚物和聚合物的官能化氟化单体的方法，可用于改善聚合物衍生系统（如涂层）的表面性能。制备官能化氟化单体的方法包括将至少一种氟化亲核试剂（如氟化醇）与至少一种含有至少一个环氧基团的化合物反应。其他方法包括将氟化醇与环状羧酸酐反应。在另一实施例中，一种方法包括将氟化甲磺酸酯、对甲苯磺酸酯或三氟甲烷磺酸酯与胺、烷氧基或苯氧基反应。在其他实施例中，该方法包括将氟化醇与烷基卤化物反应，或将氟化烷基卤化物与胺反应。这些官能化氟化单体可用作中间体，并可反应以修改其上的官能基团。此外，这些官能化氟化单体可用于与聚合物或寡聚物反应，或与具有官能基团的聚合物或寡聚物反应，通过其上的官能基团修改聚合物或寡聚物。

  A system for remediation of perfluoroalkyl substances (PFASs) has a multiplicity of β-cyclodextrins (β-CDs) and/or modified β-CDs combined with a vehicle additive, and a delivery device. Modified β-CDs can contain a single amine functionality at a single primary carbon or single secondary carbon of the β-CD. The vehicle additive can be powdered activated carbon (PAC). The delivery device is a column, a pouch, a packet, or a sheet that can permit the contacting of a fluid environment with the β-CDs and vehicle additive. The system of remediation can be used for a fluid environment or for biological organisms. CD-based fluorescent sensors can detect PFASs in the environment.

  一种用于修复全氟烷基物质（PFASs）的系统由多种 β-环糊精（β-CDs）和/或改性 β-CDs 与载体添加剂和输送装置组合而成。改性的 β-CD 可以在 β-CD 的单个伯碳或单个仲碳上含有单个胺官能团。载体添加剂可以是粉末活性炭（PAC）。输送装置可以是柱状、袋状、包状或片状，允许流体环境与 β-CD 和载体添加剂接触。修复系统可用于流体环境或生物有机体。基于 CD 的荧光传感器可以检测环境中的 PFAS。
