展开

应用
Poly(vinylidene fluoride) is useful in coatings, film, filter cloth, instrument linings, filtration membranes, pump parts, linings and valves. It is also employed as a material for transducers in devices such as headphones, microphones and sonic detectors. It is also essential for piezoelectric and electrostrictive applications. In addition, it is useful for monofilament fishing lines replacing nylon monofilament. It acts as a standard binder used in the production of composite electrodes for lithium ion batteries. It serves as a high grade insulator for wires, nanomaterials and pressure sensors. It is utilized to make filters which are used to prepare samples for high performance liquid chromatography and other advanced analytical techniques.

备注
Incompatible with strong oxidizing agents.

产品说明

一般描述

聚偏氟乙烯(PVDF)是一种具有压电、热电、铁电性质的半晶非中心对称聚合物。它是一种线性聚合物，表现出垂直于分子链方向的永久性电偶极子。这些偶极子是由于氢和氟原子对碳的电负性不同而产生的。根据工艺条件，PVDF呈现出不同的结晶相(α,β,γ,δ)。PVDF的β相表现出最佳的铁电和压电性能。

应用

聚偏氟乙烯(PVDF)用于纳米孔电极。它可用于合成嵌有碳纳米管的PVDF超细纤维复合材料。此外，它还可用于传感器、驱动器、储能、血压计、压力传感器、纳米发电机、锂离子电池等。此外，它还可作为聚偏氟乙烯-纳米粘土纳米复合材料和聚偏氟乙烯-丙烯酸橡胶/粘土纳米复合材料的基质。
