Nanographene platelet (NGP) manufacturer Angstron Materials Inc. (Dayton, Ohio) has introduced a new high-quality graphene oxide product that is available in a 0.5 percent water or solvent dispersion for processing flexibility. The single-layer graphene, with a thickness about 50,000 times smaller than the diameter of a human hair (17 microns), is said to be the thinnest, toughest material known. This single-layer graphene oxide is 0.34 to 1.0 nm thick and nearly transparent under visible light, making it suitable for use in transparent coatings. It can be used to improve thermal, electrical and mechanical properties of polymers and composites. It also enhances energy and power density in batteries and supercapacitors, enabling a higher charge storage capacity. Its average x, y dimension, based on light scattering, is 530 nm. Element analysis shows that its oxygen content is up to 46 percent. The new platelets are in stock and next-day delivery is available.
