Microwave absorption and solar evaporation have attracted significant interests and great advances have been achieved in the elimination of electromagnetic radiation pollution and production of fresh water. However, enhancing low-frequency microwave absorption properties as well as mass production of cheap solar evaporators with high evaporation rate are still facing many challenges. Herein, gamma-Fe2O3 nanocubes/graphene (GFC) composites were prepared by a facile one-step solvothermal method. GFC was mixed with paraffin to study its microwave absorption properties. The minimum reflection loss (RL) value of-59.3 dB at 2.4 GHz was achieved by GFC, while the RL value also reached-57.2 dB at 5.12 GHz with a thickness of 5.30 mm. Moreover, under matching frequency and thickness a good absorption performance (RL
