摘要：

Spawns structure of rod-like ZnO wrapped in the cellulose nanofibers was successfully fabricated through a facile one-step hydrothermal method, and their electromagnetic wave absorption properties were investigated. The structure and properties of the composite aerogel were characterized. The enlarged morphology images showed that the as-prepared cellulose nanofiber/ZnO sampleswere spawns structure of rod-like ZnO wrapped in the cellulose nanofibers. The composite aerogel in a wax matrix exhibited excellent electromagnetic wave absorption performance over 2-18GHz. The widest absorption bandwidth of 30 wt% contained with reflection loss values less than -10 dB was up to 12GHz (6-18GHz) at the thickness of 5.5mm and the minimum reflection loss value reached 26.32 dB at 15.2GHz when the thickness of the absorber was 3 mm.
