Abstract

Wollastonite (W)/carbon black (CB)/chlorinated polyethylene (CPE) conductive composites were prepared via melt compounding using CB and wollastonite as fillers and CPE as the matrix. To analyze the internal structure of the material and examine how changes in crystallinity affect the positive temperature coefficient (PTC) behavior of the composites, several characterization techniques were employed. These methods included scanning electron microscopy, X-ray diffraction, and differential scanning calorimetry. Each method provided insights into the structural adjustments and their implications for the electrical properties of the material. Special attention was given to the influence of the wollastonite content on the electrical conductivity of the composites. The results demonstrated that the lowest room-temperature resistivity (1.66 Ω·cm) was achieved with 15 wt.% wollastonite doping after 1 h of heat treatment. At the same time, the PTC strength increased to 4.7.

热处理时间对硅灰石/CB/CPE 复合材料 PTC 行为的影响
硅灰石(W)/炭黑(CB)/氯化聚乙烯(CPE)导电复合材料以炭黑和硅灰石为填料,氯化聚乙烯为基体,通过熔融复合制备而成。为了分析材料的内部结构并研究结晶度的变化如何影响复合材料的正温度系数(PTC)行为,研究人员采用了多种表征技术。这些方法包括扫描电子显微镜、X 射线衍射和差示扫描量热法。每种方法都有助于深入了解结构调整及其对材料电特性的影响。研究人员特别关注了硅灰石含量对复合材料导电性能的影响。结果表明,在热处理 1 小时后,掺杂 15 wt.% 硅灰石的室温电阻率最低(1.66 Ω-cm)。同时,PTC 强度增加到 4.7。
