Herein, the composite hydrogel based on graphene oxide (GO) and polypyrrole (PPy) and polyaniline (PANI) is fabricated via vapor-liquid interfacial synthesis. FeCl3 and GO are dispersed in an aqueous solution. Then, the polymerization of pyrrole and aniline occurs on the interface between their ...
the nanofluids prepared by graphene oxide sheets and base fluids of the water, liquid paraffin, and propyl glycol. At a concentration of 5%, the enhancements of thermal conductivity were 30.2%, 62.3% and 76.8% as the base liquids were the water, propyl glycol and liquid paraffin, respectively...
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, ...
Adsorption isotherms were used to determine the distribution of adsorbates between the liquid and solid phases. If the amount of solute adsorbed by the adsorbent is equal to the amount desorbed, the adsorption process is said to be in equilibrium52. Equilibrium isotherms are constant values that i...
liquidcrystalsself-assemblyInvestigation of the interactions between graphene oxide (GO) and biomolecules is very crucial for the development of biomedical applications based on GO. This study reports the first observation of the spontaneous formation of self-assembled liquid crystals and three-dimensional...
The noncovalent ionic liquid linkage of the CdSe/ZnS nanocrystals with the reduced gra- phene oxide (or single-walled carbon nanotubes) produced a strongly binding hybrid nanostructure, as evidenced by their efficient photocarrier generation. The nanorods demonstrated a higher photocurrent (～2 times)...
As we know, transparent electrodes are an important component in many modern electronic devices such as touch screen, liquid crystal display (LCD), light-emitting diode (LED) and solar cells. In addition, all of electronic appliances are growing in demand too much fast due to the rapid ...
Water disinfection materials should ideally be broad-spectrum-active, nonleachable, and noncontaminating to the liquid needing sterilization. Herein, we demonstrate a high-performance capacitive deionization disinfection (CDID) electrode made by coating an activated carbon (AC) electrode with cationic nanoh...
synthesis route and the material used as carbon source. In addition, highly oxidized fragments, called oxidative debris, OD, are produced during theoxidation process. These fragments are adsorbed onto the graphene oxide network and can be removed by alkaline washing. The purified material has lower...
Although there remain many obstacles for graphene and its derivatives (e.g., graphene oxide, functionalized graphene) for real membrane applications, graphene will continue to make rapid progress in membrane applications, particularly, such as gas and liquid separations. This article will cover ...
