摘要	Developing strong electromagnetic (EM) wave absorbing materials to solve the issue of EM radiation emanating from electronic devices in low-frequency range remains currently a great challenge. The majority of current solutions in low-frequency range are based on magnetic absorbent. However, this approach is constrained by the poor impedance matching, high production cost and limited absorption bandwidth. Herein, the novel reproducible cellulose-derived flawed graphite carbon material (represented as CFGC) was prepared by chemical and following simple carbonization method. Besides, the unique defect structure and the mechanism underlying microwave absorption (MA) are elaborated in detail. By fine-tuning the content of CFGC, the MA property is optimized. The minimum reflection loss (RLmin) of 50 wt% filling for CFGC is -42.08 dB at 4.08 GHz, showing an excellent MA property within the low-frequency range of C bands. Thus, the novel CFGC in this study provides a new and convenient way to solve low-frequency EM pollution.
