Abstract
Functionalization of polyallylamine (PAA) on graphene oxide (GO) surface is demonstrated using the optical spectroscopic measurements. The disappearance of C-OH and C-O vibrational modes of GO, and appearance of new N-H peak in the Fourier transform infrared spectra of PAA, indicates the chemical interaction of GO with PAA to form GO-PAA composite. The optical behavior of GO-PAA composite recorded through the UV-Vis absorption and photoluminescence for different optical excitations show individual properties of GO and PAA. The enhanced electrical conductivity through GO-PAA thin film based aluminum (Al)/GO-PAA/indium-tin-oxide (ITO) device structure is attributed to the reduction of GO sheets after functionalization with PAA.
