研究目的
Investigating the enhancement of attenuation characteristics against electromagnetic radiation through controllable coating of polypyrrole on silicon carbide nanowires.
研究成果
The study successfully demonstrated that coating SiC nanowires with PPy shells significantly enhances their dielectric properties and electromagnetic absorption performance. The composite loaded with 5 wt% of PPy@SiC nanowires achieved an effective EA bandwidth of 6.88 GHz and a strongest reflection loss of ?58.6 dB, indicating its potential for electromagnetic protection applications.
研究不足
The study focuses on the enhancement of electromagnetic absorption properties through the coating of PPy on SiC nanowires, but does not explore the effects of other coating materials or the scalability of the synthesis process.
