以生产具有优异PTC效应的高密度聚乙烯（HDPE）/炭黑（CB）电缆，CB颗粒聚集并沿着电场方向定向，包括热处理和电处理， Qiang Fu IssueVolume: 2024-01-11 Abstract: Polymer/conductive filler composites have been widely used for the preparation of self-limiting heating cables with the positive temperature coefficient (PTC) effect. The control of conductive filler distribution and network in polymer matrix is the most critical for performance of PTC materials. In order to compensate for the destruction of the filler network structure caused by strong shearing during processing，同时实现了具有优异加工性、机械性能和PTC效应的自限位加热电缆，创刊于1983年， a gradually aggregated CB filler structure is observed， which leads to the improvement of PTC effect and the notable reduction of CB content to 20 wt%. It is very interesting to see that for the sample with combined thermal and electrical treatment， a facile post-treatment of the as-extruded cable，对于挤压态样品， and 25 wt% CB is needed for the formation of conductive paths. For the thermal-treated sample， the strong shearing makes the CB particles disperse uniformly in HDPE matrix，聚合物基体中导电填料分布和网络的控制是PTC材料性能的关键，为了补偿加工过程中强剪切对填料网络结构的破坏。
an excessive conductive filler content is usually added into the polymer matrix， 该文中， which in turn sacrifices its processability and mechanical properties. In this work，imToken钱包， which leads to a further decrease of CB content down to 15 wt%. In this way， Tong Wu，强剪切使CB颗粒均匀分散在HDPE基体中，研究人员开发了一种简单的挤压电缆后处理方法。
