TL;DR: In this paper, a novel 4,4′-diaminostilbene-2,2′-disulfonic acid (DASDSA)-functionalized reduced graphene oxide (DasDSA-rGO) was prepared via simple refluxing method involving GO and DSA in the presence of ammonia solution followed by reduction with hydrazine hydrate FTIR spectroscopy, Raman scattering, X-ray photoelectron spectroscope (XPS), and XRD analyses confirmed the successful functionalization and reduction of GO in DAS

TL;DR: In this article, a 2D transition-metal-based nanomaterial is constructed as a novel electrode material for asymmetric supercapacitor application, which displays an excellent areal capacitance of 7.82% at a current density value of 3.5m.

TL;DR: In this article, the dielectric properties of the synthesized samples were studied via impedance measurements in the frequency range of 100 Hz −7 MHz at room temperature. But the authors did not consider the effect of pH values on the performance of the samples.

TL;DR: In this article, an acid-vapour-mediated method to functionalize the inert TEG surface with oxygen functional groups was developed, and the effects of oxygen functional group on the capacitive performances of TEG were investigated with various reaction times.

TL;DR: In this article, a modified graphene oxide/polyethyleneimine reactive layer-by-layer self-assembling film for the hydrogen barrier was fabricated by the covalent bond self-assembled technology.
