An ultralight graphene oxide (GO)/polyvinyl alcohol (PVA) aerogel (GPA) is proposed as a new class of acoustic materials with tuneable and broadband sound absorption and sound transmission losses. The interaction between GO sheets and PVA molecules is exploited in our environmentally friendly manufact...
S5). The interlayer spacing measurement using X-Ray Diffraction (XRD) is consistent with mass uptake data showing monotonic increase of interlayer spacing of GO from 6.5 Å to 10 Å by changing humidity from 0 to 100%31. For the purpose of coating GO on a printed graphene RFID ...
Graphene oxide (GO) is a highly oxidized form of chemically modified graphene that consists of single atom thick layer of graphene sheets with carboxylic acid, epoxide and hydroxyl groups in the plane. From: Journal of Controlled Release, 2014 ...
Graphene oxide (GO) is a promising material for energy storage device applications. Modified Hummers method (MHM) has been used to prepare GO films from graphite flakes by Sol-Gel method. With the aid of bridging agent dimethyldichlorosiline, structurally fine GO films were prepared. Fourier tran...
Chitosan, modified with different dosages of graphene oxide (GO) and reduced graphene oxide (rGO), was first prepared, and its adsorption capacity for reactive red (RR) dye in aqueous solutions was investigated, in this paper. The structure and morphology of the adsorbents were characterized by...
In this work, hybrid monolith aerogels of chitosan (CTS), an environmentally-benign biopolymer, with different amounts of graphene oxide (GO) are prepared using freeze-drying. The sorption performance of the developed aerogels for CO2capture is studied. The aerogels are characterized by X-ray ...
Investigation of graphite and graphene oxide XRD Figure 5 obviously depicts the XRD pattern of graphite and graphene oxide. Based on the figure, for the graphene oxide, an intense peak is seen around 10.9° which is the characteristic peak of pure GO. In addition, comparison of the GO and ...
Graphene oxide is highly desired for printing electronics, catalysis, energy storage, separation membranes, biomedicine, and composites. However, the present synthesis methods depend on the reactions of graphite with mixed strong oxidants, which suffer from explosion risk, serious environmental pollution, ...
