Canrd's graphene oxide solution GOs-325 is developed for advanced materials research, particularly in electrochemistry, composites, and coating applications. Prepared via the improved Hummers method, this aqueous dispersion offers high purity, uniform dispersion, and abundant oxygen-containing functional groups. Available in 2 g/L concentrations with 100 mL or 500 mL volumes, it can be used directly in solution form. Its properties make it suitable for use in energy storage devices (such as supercapacitors and lithium batteries), conductive inks, antistatic materials, electromagnetic shielding, thermal management, anticorrosive coatings, catalyst and drug carriers, sensors, and adsorbents. This product provides a reliable platform for exploring two-dimensional carbon materials in laboratory settings.
