Description
Summary:[Display omitted] •PMMA films containing both Ag-NWs and GONPs were formed by using a transfer method.•Scanning electron microscopy images showed that the Ag-NWs on the PMMA film were partially covered with the GONPs.•Transmittance and the sheet resistance of the PMMA films were approximately 90% at 550nm and 24Ω/sq, respectively.•Uniformity of the sheet resistance was significantly improved due to the GONP treatment.•XPS spectra showed that the enhancement in the sheet resistance originated from the quaternary nitrogen in the GONPs. Nanocomposite films containing silver nanowires (Ag NWs) and graphene-oxide nanoplatelets (GONPs) were formed on glass, and the nanocomposite films were then transferred to poly(methylmethacrylate) (PMMA) films. Scanning electron microscopy images showed that Ag NWs with a length of 20μm and a width of 80nm, together with GONPs with a size of 15μm, had been formed on the PMMA film and that the Ag NWs on the PMMA film were partially covered with the GONPs. While the transmittance of the PMMA film with the Ag NWs and the GONPs was almost the same as that of the PMMA film with the Ag NWs alone, the corresponding sheet resistance was decreased due to the generation of quaternary nitrogen in the GONPs, which the results of X-ray photoelectron spectroscopy and Raman spectroscopy confirmed. The transmittance and the sheet resistance of the PMMA film containing Ag NWs and GONPs were approximately 90% at 550nm and 24Ohm/sq, respectively.
