As described in the Introduction, the EM absorption performance is determined by the constituent component and nanostructure of the EM absorbers. Previous studies have shown that the direct utilization of the biomass for fabricating EM absorbers results in poor EM absorption due to its poor dielectric loss. The biomass has to be graphitized to enha...
Past research has reported the conversion of cellulose and lignin from LCNFs into graphitized carbons during carbonization . In our next set of experiments, we carbonized the above LCNFs, i.e., LCNFs-4, LCNFs-5, LCNFs-8, and LCNFs-30, to obtain carbonized materials, namely GC-4, GC-5, GC-8, and GC-30, respectively. The structure of the GC-4, GC-5, ...
Next, we sought to investigate the effects of the obtained carbon materials' structure and composition on their EM absorption performance. Figure 5 shows the EM absorption performance of GCs with a broad thickness of 1.0–5.0 mm. EM absorbers are required to exhibit a broad frequency absorption region (termed as an effective absorption region) with ...
In the final set of experiments, we sought to test the hydrophobicity and acid/base stability of GC materials under real environmental conditions. As shown in Fig. 7a, the apparent contact angle of water droplets on an EM film consisting of 15% GC-8 was measured to be ~ 135°, suggesting an enhanced hydrophobicity. We attribute the enhanced hydropho...
