摘要：

Graphene oxide (GO), products with various proportions of polyvinyl alcohol (PVA), was characterized to obtain verified patterns of reduced graphene oxide. FT-IR spectra indicated that PVA could lower the reduction temperature of GO by at around 70 degrees C. New peaks near D band and overlapped G band in the Raman spectra appear to indicate that some parts of PVA interact with GO. The sheet resistance of GO/PVA showed that the GO/PVA ratio was optimal between 1/0.25 and 1/2. Using GO/PVA, we printed a line on PET, and after annealing at 140 degrees C, it achieved a resistance of 23 k Omega/cm. (C) 2015 Elsevier B.V. All rights reserved.
