| 摘 要： | 聚偏氟乙烯(PVDF)及其一些共聚物,例如偏氟乙烯-四氟乙烯共聚物(PVDF/TFE)经过处理后呈现较强的压电性。许多研究表明它们是铁电聚合物,而且压电活性与样品的高次结构有关。松弛谱是研究结晶高聚物的高次结构的有力工具,近来,Koizumi等人报道了PVDF/TFE的热处理与松弛现象的关系。本文作者也报道了

| Abstract: | The effect of high temperature annealing on the higher order structure of a copolymer of vinylidene fluoride and tetrafluoroethylene (TFE 2.8 mol %) has been studied by various method, primarily dynamic mechanical, by also dielectric and microspic. The controversy on the origin of a relaxations is discussed from the point of view of higher order structure studies. |
