Investigation of Electromagnetic Shielding Effectiveness of Nanostructural Carbon Black/ABS Composites
Abstract: With the increasing application in electromagnetic interference shielding field of high polymer materials, there is an increasing interest in investigating of high polymer composites. The effects of carbon black fraction on volume resistivity and electromagnetic shielding effectiveness (SE) of nanostructural carbon black (CB)/Acrylonitrile Butadiene Styrene (ABS) composites were studied. The results indicated that when CB mass fraction was over 15%, the volume resistivity dropped sharply and when it rose to 35%, the volume resistivity achieved the lowest value 103 Ω?cm and the SE was about 6 dB. In addition, there are two obvious percolation effect at 15% ~ 20% and 30% ~ 35% CB respectively in the course of the volume resistivity changing.
