摘要
将二茂铁与可膨胀石墨混合物在高温下膨化,制备了附着铁氧化物的磁性膨胀石墨.利用同轴法兰法测试了掺磁性膨胀石墨水泥浆体的电磁屏蔽效能(SE).结果表明:掺加磁性膨胀石墨能大幅提高水泥浆体电磁屏蔽效能;掺15%磁性膨胀石墨水泥浆体电磁屏蔽效能值最高可达30.2dB.
Magnetic expanded graphite attached with iron oxide was prepared by expanding ferrocene and expandable graphite mixture at high temperature. The electromagnetic shielding effectiveness（SE） of cement paste added with magnetic expanded graphite was tested by the coaxial flange method. Results show that the SE of cement paste added with magnetic expanded graphite can be substantially increased. The best SE of cement paste added with magnetic expanded graphite of 15%（by mass） is 30.2dB.
