Carbonized foams from graphene/phenolic resin composite aerogels for superior electromagnetic wave absorbers

发表刊物：Ceramics International
摘要：Ultralight graphene/phenolic resin composite aerogels (GPFs) were prepared through the chemical reduction
and self-assembly of graphene oxide (GO) in water-soluble phenolic resin, followed by a freeze-drying process;
carbonized foams (GPFs(T)) were obtained by the subsequent heat treatment of GPFs at a relatively low tem-
perature (500–700 ◦ C). Although GPFs do not show the qualified reflection loss value of below −10dB, GPFs(T)
achieve the greatly enhanced electromagnetic-wave absorbing performance. Specifically, the minimum reflection
loss value of GPF 1 (500) reaches −22.7 dB at 14.4 GHz with the absorber thickness of 2.0 mm and the effective
absorption bandwidth is up to 5.4 GHz (12.4–17.8 GHz). The evolution of electromagnetic-wave absorbing
properties from GPFs to GPFs(T) at different temperatures related with different graphene content is explored.
GPFs(T) are expected to exhibit high thermal stability and excellent corrosion resistance property, and especially
still maintain u
