“…Graphene oxide was synthesized through the modified Hummers method [37] as stated in our previous reports [2,18,38]. Prior to reduction, the synthesized graphene oxide (0.15 g) was dispersed in 50 mL of deionized water by ultrasonic treatment (1,000 W, 40 kHz) for 2 h, and then, the yellow-brown dispersion was poured into a polytetrafluoroethylene (PTFE) plate with a diameter of 11.5 cm and heated at 80°C for 24 h. Finally, the brown-black films with a diameter of 10 to 11 cm and thickness of 10 μm could be obtained as shown in Figure 1a.…”

In this paper, we have reported that paper-like graphene-Ag composite films could be prepared by a facile and novel chemical reduction method at a large scale. Using ascorbic acid as a reducing agent, graphene oxide films dipped in Ag+ aqueous solutions can be easily reduced along with the decoration of different sizes of Ag particles distributed uniformly. The results reveal that the obtained films exhibit improved mechanical properties with the enhancement of tensile strength and Young's modulus by as high as 82% and 136%, respectively. The electrical properties of graphene-Ag composite films were studied as well, with the sheet resistance of which reaching lower than approximately 600 Ω/□. The graphene-Ag composite films can be expected to find interesting applications in the area of nanoelectronics, sensors, transparent electrodes, supercapacitors, and nanocomposites.

“…In recent years, paperlike flexible materials, especially graphene‐based papers (GBPs), have attracted more attention because of their potential applications, such as those in viscoelastic materials, fuel cells, membranes, supercapacitors, lithium batteries, and electrochemical sensors . The electrochemical activity of graphene paper (GP) is not enough for technological applications, and metal nanoparticles, metal oxide nanoparticles, carbon nanomaterials, polymers, and dyes can be doped to GPs with various amounts to tune their physical properties and increase their electrical conductivity and electrochemical activity.…”

Surface‐confined electropolymerization allowed us to easily prepare homogeneous polymer composite paper structures. The fabrication of freestanding graphene (Gr)‐based composite electrodes is very important for many modular approaches in electrochemical applications, such as fuel cells, supercapacitors, and sensors. A Gr composite paper electrode doped with polymeric films of pyronin Y was fabricated by two repetitive simple applications: vacuum filtration and surface‐confined electropolymerization. The characterization of this composite paper was done with scanning tunneling microscopy, scanning electron microscopy, X‐ray photoelectron spectroscopy, powder X‐ray diffraction spectroscopy, Raman spectroscopy, UV–visible absorption spectroscopy, four‐point probe conductivity measurement, cyclic voltammetry, and electrochemical impedance spectroscopy. The freestanding composite paper demonstrated good electrocatalytic activity for the electrooxidation of dopamine; this indicated that this composite paper could be used for the amperometric quantification of dopamine in real samples. © 2017 Wiley Periodicals, Inc.
