摘要：

Fullerenes (C60) exhibits many advantageous properties but its poor solubility seriously restricts its applications. In this paper, C60 is dissolved in graphene oxide (GO) aqueous solution homogenously. This water-soluble composite material of GO/C60 is used for making a capacitive humidity sensor. This sensor shows a sensitivity of three times larger than that of the sensor based on C60 film. The possible reason is that C60 is uniformly adsorbed on the surface of GO, thus reducing the agglomeration of C60. This is supported by TEM, FTIR, and complex impedance test.
