Reduced graphene oxide (rGO) has attracted significant attention as an active electrode material for sensors and flexible energy devices due to its high electric conductivity and large surface area. rGO is usually obtained from graphene oxide(GO) through a thermal, chemical, photochemical, and electrochemical reduction process. Compared to the othe...

Reduced graphene oxide (rGO) has attracted attention as an active electrode material for flexible electrochemical devices due to its high electric conductivity and large surface area. Compared to other reduction processes, laser reduction is a precise, low-cost, and chemical-free process that is directly applied to graphene oxide (GO) membranes. Th...

Graphene oxide (GO) membranes are promising materials for water filtration applications due to abundant nanochannels in the membrane structure. Because GO membranes are unstable in water, metal cations such as Al3+ are often introduced to the membrane structure to promote cross-linking between individual GO sheets. Here, we describe a simple yet ve...

Graphene oxide (GO) membranes, which form from the lamination of GO sheets, attract much attention due to their unique nanochannels. There is much interest in controlling the nanochannel structures and improving the aqueous stability of GO membranes so they can be effectively used in separation and filtration applications. This study employed a sim...

... To improve stability, metal cations are often introduced to the membrane structure to promote crosslinking between individual GO planes. In paper [5], GO membranes were modified with Al 3+ from three different sources: alumina, aluminum chloride, and aluminum foil. It was showed that the membranes functionalized with Al 3+ from aluminum foil were the most stable in water under mechanical stress; hence, the source of the modifier matters greatly. ...
... Free-standing GO membranes [12] with varying thicknesses between 10 and 16 µm were adhered on flexible substrates with GO solution and left to dry overnight. The GO membrane was reduced using a conventional CO 2 laser engraver (Epilog Fusion Pro, wavelength: 1065 nm) under ambient conditions (21 • C, 30% RH). ...
