摘要MoS2 nanospheres have been synthesized by a hydrothermal method at various reaction times using sodium molybdate and thioacetamide as the sulfur source and reducing agent, respectively. The prepared MoS2 nanospheres have been characterized by XRD, SEM and vector network analyzer, respectively. Results show that the prepared MoS2 samples were the flower-like nanospheres and the powder size increased with increasing reaction time. The real part (epsilon') and imaginary part (epsilon") of permittivity of the prepared MoS2 nanospheres increased as the reaction time increased initially and decreased afterwards. When the reaction time was 20 h, the epsilon' and epsilon" reached the maximum values, 8.25-8.05 and 4.1-3.85, respectively. The minimum reflection loss value of -45dB was achieved at 8.3 GHz for the synthesized MoS2 nanospheres with reaction time of 16 h. All the samples with matching thicknesses of 2-4 mm presented wider effective absorption bandwidths (RL < -10dB) in the frequency range of 8.2-12.4 GHz.
