本文描述了咪唑纳米二氧化硅的合成及其在微波照射下作为热源的作用。制备了一系列具有不同反阴离子的改性纳米粒子，并比较了它们在微波辐照下的增强加热能力。最后，我们总结了咪唑阳离子与水分子相互作用产生的介电损耗在加热效应中起着至关重要的作用。
We describe here the synthesis of imidazolium-presenting silica nanoparticles and the role as a heating source under microwave irradiation. The series of modified nanoparticles with various kinds of counter anions were prepared, and their enhancement abilities of heating under microwave irradiation were compared. Finally, we summarized that the dielectric loss originated from the interaction between imidazolium cation and water molecules should play a crucial role in the heating effect.
