Composite material preparation techniques based on electric field induced filler orientation
The electric field orientation method,as an effective method to improve the performance of composite materials,has become a key technology for preparing composites with excellent performance under low filling conditions,and has received widespread attention from many scholars at home and abroad.A theoretical analysis of the orientation of fillers induced by electric fields was provided,and the relevant research on the preparation of composite materials induced by different types of electric fields to induce different orientations of fillers was summarized and analyzed.Focusing on the thermal breakdown phenomenon during the orientation process of DC electric field and AC electric field,the research status and advantages of pulse electric field induced filler orientation preparation of oriented composite materials were mainly discussed.Finally,the difficulties in preparing composite mate-rials using electric field orientation method were analyzed,and the future development direction of electric field orientation method for preparing composite materials was prospected.
