Abstract:
Amide functionalized graphene oxide (AGO) was synthesized by chemical method at room temperature. Fourier transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy measurements were carried out to verify the functionalization. Thin films of graphene oxide (GO) and AGO were formed by spin coating on SiO2/p-Si (100) substrate. The variation in the I-V characteristics was recorded at different humidity level. It has been observed that in GO the variation in resistance with humidity is relatively small as compared to AGO. The resistance of the AGO film was approximately 9.87 kΩ at 10% relative humidity (RH), and decreases to 1.5 kΩ at 90% RH.
