Abstract
Chemical graphitized r-GOs, as the thinnest and lightest material in the carbon family, exhibit high-efficiency electromagnetic interference (EMI) shielding at elevated temperature, attributed to the cooperation of dipole polarization and hopping conductivity. The r-GO composites show different temperature-dependent imaginary permittivities and EMI shielding performances with changing mass ratio.
摘要
化学石墨化 r-GO，作为碳家族中最薄最轻的材料，在高温下表现出高效的电磁干扰（EMI）屏蔽性能，这归因于偶极子极化和跳跃电导的协同作用。r-GO 复合材料的复数介电常数和 EMI 屏蔽性能随质量比的变化而呈现不同的温度依赖性。
