聚偏氟乙烯(PVDF)膜与一些有机弱碱作用脱氟化氢(HF)生成表面为聚一氟乙炔(PFA)的膜.红外、紫外可见光谱分析表明脱HF的PVDF膜的共轭链结构比较规整.X光电子能谱、反应深度和接触度的分析表明,PVDF脱HF反应主要发生在膜表面,脱HF的PVDF膜(PFA)经各种掺杂剂掺杂后电导率上升5~6个数量级,最高可达10~(-4)S/cm,且在掺杂过程中表现出的性质不同于聚乙炔.
Polyvinylidene fluoride (PVDF) membrane and some organic weak bases Hydrofluorination (HF) generated surface is polyfiuoroacetylene (PFA) membrane.Fluorescence and UV-visible spectroscopy analysis showed that the de-HF PVDF membrane conjugate chain structure comparison Regularity.X-ray photoelectron spectroscopy, reaction depth and contact analysis showed that the PVDF HF removal reaction occurred mainly on the surface of the membrane, and the desorption rate of PVDF membrane (PFA) with various dopants increased by 5 ~ 6 The order of magnitude is up to 10 -4 S / cm, and the properties exhibited during doping are different from those of polyacetylene.
