Polyvinylidene fluoride (PVDF) is a modern polymer material used in a wide variety of ways. Thanks to its excellent resistance to chemical or thermal degradation and low reactivity, it finds use in biology, chemistry, and electronics as well. By enriching the polymer with an easily accessible and cheap variant of graphite, it is possible to affect the ratio of crystalline phases. A correlation between the ratios of crystalline phases and different properties, like dielectric constant as well as piezo- and triboelectric properties, has been found, but the relationship between them is highly complex. These changes have been observed by a number of methods from structural, chemical and electrical points of view. Results of these methods have been documented to create a basis for further research and experimentation on the usability of this combined material in more complex structures and devices.
聚偏二氟乙烯（PVDF）是一种用途广泛的现代聚合物材料。由于其对化学或热降解具有出色的抗性且反应活性低，它在生物学、化学和电子学领域也有应用。通过用一种易于获取且廉价的石墨变体来增强这种聚合物，可以影响晶相比例。已经发现晶相比例与不同性质（如介电常数以及压电和摩擦电性质）之间存在关联，但它们之间的关系非常复杂。从结构、化学和电学角度，通过多种方法观察到了这些变化。这些方法的结果已被记录下来，为进一步研究和试验这种复合材料在更复杂结构和器件中的可用性奠定基础。
