摘要

杜邦公司最近以Teflon AF的商标名推出了一种新型的四氟乙烯和全氟-2,2-二甲基-1,3-二唑的非晶态共聚物。由于这些聚合物在波长约为3 /spl mu/m的情况下具有很高的光学透明度，因此正在研究并用于许多应用，主要是在光学领域。聚四氟乙烯AF可以溶解在氟碳溶剂中，并采用等温和热激放电测量研究了自旋涂覆聚四氟乙烯AF薄膜。并与其他聚四氟乙烯含氟聚合物的相应性能进行了比较。在相同电场下，聚四氟乙烯AF的长期电荷存储能力与其他聚四氟乙烯材料相似。

Electret properties of spin-coated Teflon-AF films

Novel amorphous copolymers of tetrafluoroethylene and perfluoro-2,2-dimethyl-1,3-dioxole were recently introduced by DuPont under the trade name Teflon AF. These polymers are being studied and used for a number of applications mostly in optics, since they exhibit high optical transparency up to a wavelength of about 3 /spl mu/m. Teflon AF may be dissolved in fluorocarbon solvents and spin-coated Teflon-AF films were studied using isothermal and thermally stimulated discharge measurements. Results are presented and discussed in comparison with the corresponding properties of the other Teflon fluoropolymers. The long-term charge-storage capability of Teflon AF is similar to that of the other Teflon materials for the same electric fields.<>
