摘　　要：生物炭材料因高的电导率而具有吸收电磁波的潜在优异性能,但其吸收性能的提高受阻抗失配制约.为了解决此问题,通常在生物炭材料中加入磁性材料,以提高吸波性能.通过简单的浸渍和烧结,制备铁基生物炭(樟树叶)复合材料.研究结果表明:相对于其他6种铁基生物炭复合材料,该文制备的铁基生物炭复合材料具有较强的综合吸波性能.Biochar materials potentially possess excellent electromagnetic wave absorption properties due to their high conductivity.However,the enhancement of their absorption properties is constrained by impedance mismatch.To address this issue,magnetic materials were typically incorporated into biochar materials to enhance their wave absorption capabilities.Iron-based biochar(Cinmamomum cam phora leaf)composites were fabricated via straightforward impregnation and sintering processes.The research result indicated that compared with the other six iron based biochar composites,the iron-based biochar composites developed in this study exhibit strong integrated wave absorbing properties.
