Graphene oxide (GO) with its unique two-dimensional structure offers an emerging platform for designing advanced gas separation membranes that allow for highly selective transport of hydrogen molecules. Nevertheless, further tuning of the interlayer spacing of GO laminates and its effect on membrane separation efficiency remains to be explored. Here, positively charged fullerene C derivatives are electrostatically bonded to the surface of GO sheets in order to manipulate the interlayer spacing between GO nanolaminates.

Organized microfibrillation is a method for optically printing well-defined porosity into thin polymer films with ultrahigh resolution. Here we demonstrate this method to create self-enclosed microfluidic devices with a few simple steps, in a number of flexible and transparent formats.

- * The study highlights how thermodynamic issues and the size of side groups affect the PUs' morphology and overall properties.
- * Increased 1,2-vinyl content results in better phase mixing and smaller microdomains, which leads to more complex pathways for gas molecules, ultimately reducing gas permeability in the membranes.
Article Synopsis
- * Researchers have found a way to control this microfibrillation by using standing-wave optics to create a periodic stress field, allowing for the intentional development of layered structures within the polymer films.
- * This innovative technique not only produces vibrant multi-layered structures with tunable colours but also enables an inkless, high-resolution printing method, achieving up to 14,000 dots per inch on various flexible and transparent materials.
