| 摘 要： | 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^-^4s/cm, 且在掺杂过程中出现出的性质不同于聚乙炔。

Study on preparation, characterization and electrical property of dehydrofluorinated poly (vinylidene fluoride) film |

| Abstract: | The reactions of poly (vinylidene fluoride) (PVDF) film with some organic weak bases produce dehydrofluorinated product-polyfluorinated acetylene (PFA) on the two surfaces of the film. An orderly conjugated structure of the dehydrofluorinated film is suggested by IR and UV-VIS spectra. Inestigations by XPS, reaction depth and contact-angle hysteresis indicated that the two surfaces of PVDF film are the main reaction site. The conductivity of the dehydrofluorinated PVDF films are raised 5~6 magnitude of orders after doping by various dopants. The maximum value reaches 10^-^4s/cm. The doping behavior of the dehydrofluorinated PVDF film is different from that of polyacetylene. |
