一种高介电常数碳纳米纤维改性PB‑1膜的制备方法
摘要：
一种高介电常数碳纳米纤维改性PB‑1膜的制备方法。本发明属于聚烯烃材料加工技术领域，具体涉及一种高介电常数碳纳米纤维改性PB‑1膜的制备方法。本发明目的是为了解决目前PB‑1薄膜介电常数不高的问题。方法：一、碳纳米纤维预处理；二、碳纳米纤维/聚丁烯‑1颗粒的制备；三、热压成片；四、拉伸成膜；五、冷却定型。本制备工艺简单易行，制备的薄膜具有无杂质、厚度均匀的特点。同步双向拉伸制备的碳纳米纤维/PB‑1膜的介电常数在103Hz频率下可达36.15，介电常数大幅度增加。
摘要（英）：

The invention provides a preparation method of a carbon nanofiber modified PB-1 film with high dielectric constant, belongs to the technical field of polyolefin material processing and aims to solve the problem that at present the dielectric constant of PB-1 films is not high. The method comprises the steps of one, carbon nanofiber pretreatment; two, carbon nanofiber/polybutylene-1 granule preparation; three, hot-pressing sheeting; four, stretching film formation; five, cooling shaping. The preparation technology is simple and easy to implement, and the prepared film has the characteristics of no impurity and uniform thickness. The dielectric constant of the carbon nanofiber/PB-1 film prepared by synchronous two-way stretching can reach 36.15 under the frequency of 103 Hz, and the dielectric constant is increased greatly.
