Carbon nanofilm stabilized twisty V2O3 nanorods with enhanced multiple polarization behavior for electromagnetic wave absorption application
文献摘要：
Vanadium(V)oxides exhibit low electrical conductivity and poor polarization properties,especially in that V2O3 has low stability and is easily oxidized to higher valence V oxides.To solve this problem,we herein provide a two-step strategy for the synthesis of carbon nanofilm stabilized twisty V2O3 nanorods(V2O3@C),including a hydrothermal reaction and a controlled pyrolysis process.Conductivity tests and electron-spin resonance(ESR)spectra indicate that the coating of carbon nanofilm not only enhances the electrical conductivity but also generates abundant defects.The electromagnetic waves absorption(EMA)results suggest that V2O3@C exhibits excellent EMA performance at ultra-low thickness,where the ef-fective absorption bandwidth gets to 7.21 GHz at 1.7 mm and the maximal absorption reaches-56 dB.Enhanced conductivity loss and improved multiple polarization relaxation were used to illustrate the ab-sorbing mechanism of V2O3@C.This work provides new insights into the design of advanced nanocom-posites for EMA applications.
