摘要: 本論文於研究泡沫碳製作用於電磁波遮蔽。採用物理發泡法製備閉孔酚醛泡沫, 通過調整固化劑含量、發泡溫度、保溫時間等方法製得孔隙率可調、孔洞分布均匀的閉孔酚醛泡沫,再經過1000℃碳化,取得碳泡沫。並且測試不同孔隙率、孔徑和厚度對泡沫碳的電磁屏蔽效能。结果說明:泡沫碳具有優良的電磁波屏蔽效能,頻率10~3000MHz内,在泡沫碳d(孔徑)=0.24mm、θ(孔隙率)=67.3%、h(厚度)=3mm時,電磁屏蔽效能可達到16dB;d(孔徑)=0.31mm、θ(孔隙率)=70.4%、h(厚度)=12mm時,泡沫碳的電磁屏蔽效能可達到50dB,且隨著孔隙率、孔徑的增加,泡沫碳的電磁屏蔽性能下降;隨著厚度的增加,泡沫碳的電磁屏蔽效能則增加。
