Effect of Magnetic Field Treatment on Dielectric Properties of LDPE Composites with Carbon Nanotube and Nano Graphite

摘要：

　　Magnetic phenomenon is one of the most fundamental phenomena of substances.All substances possess strong or weak magnetic property, and have different responds to external magnetic field.Development of high performance materials by using external magnetic field is an important research field of material science.In this study, a static magnetic field is applied during thermoforming processing of low density polyethylene (LDPE)/carbon nanotube (CNT), LDPE/nano graphite composites.The effect of magnetic field treatment on dielectric property of these composites is investigated.Experimental results indicate that CNT and nano graphite orientate in melted LDPE under the magnetic field.The electrical conductance, the dielectric constant and the dielectric loss angular tangent value of LDPE/CNT and LDPE/nano graphite composites along the magnetic field direction all increase.
