摘要

未掺杂α-MnO2的MnO6八面体偶极子含量低，限制了其介电损耗能力。在此，我们通过两步水热法开发了具有扭曲MnO6八面体的质子化MnO2以增加偶极子数。与α-MnO2相比，该质子化MnO2的偶极子极化损耗能力大大提高，在低厚度为2 mm时，反射损耗值为-19.1 dB，有效吸收带宽为3.3 GHz。

Enhanced dielectric losses in α-MnO₂via protonation modulation.

MnO₆ octahedra without distortions in α-MnO₂ have a low dipole content, which limits their dielectric loss capabilities. Herein, we develop protonated MnO₂ with distorted MnO₆ octahedra for increased dipole numbers via a two-step hydrothermal method. In comparison with α-MnO₂, this protonated MnO₂ provides greatly improved dipole polarization loss capabilities, resulting in a reflection loss value of -19.1 dB with an effective absorption bandwidth of 3.3 GHz at a low thickness of 2 mm.
