聚偏氟乙烯基复合材料的制备方法
摘要：
聚偏氟乙烯基复合材料的制备方法，它涉及一种复合材料的制备方法。本发明是为了解决现有在低体积浓度(≤10％)陶瓷类填料下聚偏氟乙烯基复合材料介电常数不高的技术问题。本方法如下：一、晶化处理；二、施镀；三、熔融共混；四、磁化处理。本发明选用负载Ni壳的钛酸铜钙为填料，以PVDF为基体，在低体积浓度(≤10％)填加量下采用熔融共混-热压成型工艺，结合磁化处理手段，制备得磁化的PVDF/CaCu3Ti4O12@Ni复合材料，其介电常数高达12000～18000，并且该材料能保持聚合物基体所具有的优良机械性能。本发明属于复合材料的制备领域。
摘要（英）：

The invention belongs to the field of composite material preparation, and relates to a preparation method of a composite material, in particular to a preparation method of a polyvinylidene fluoride matrix composite material. The technical problem that the dielectric constant of a polyvinylidene fluoride matrix composite material in existing ceramic padding with the low volume concentration (smaller than or equal to 10%) is not high is solved. The preparation method comprises the steps of crystallization, plating, melt blending and magnetization. Load Ni shell copper calcium titanate is selected as padding, PVDF is used as a matrix, the melt blending-hot pressing forming technology is adopted on the adding amount with the low volume concentration (smaller than or equal to 10%), magnetization is adopted as well, and therefore magnetized PVDF/CaCu3Ti4O12@Ni composite material is obtained. The dielectric constant of the composite material reaches up to 12000-18000. The composite material can keep the good mechanical performance of a polymer matrix.
