由于Teflon AF具有气体渗透性结构、 疏水性、 化学惰性、 比水低的折射率等特点， 因此Teflon AF液芯波导在吸收、 荧光、 拉曼光谱分析、 气体传感器等诸多领域得到了广泛的应用。 本文将剖析Teflon AF液芯波导的特性， 分析Teflon AF液芯波导的应用研究进展， 展望Teflon AF液芯波导的应用研究前景。

Teflon AF is chemically very inert, quite physically and optically stable, a highly vapor-permeable polymer with optical transparency through much of the UV-Vis region and with an RI lower than that of water, so Teflon AF LWCC/LCW (Long path-length liquid waveguide capillary cell/liquid core waveguides) has been used with a range of different detection techniques, including absorbance spectroscopy, fluorescence spectroscopy, Raman spectroscopy, and gas sensor. The present article describes the properties and the aspects of Teflon AF LWCC/LCW instrumentation and applications. And finally，the future prospect and outlook of Teflon AF LWCC/LCW is also discussed．
