ABSTRACT:
Carbon nanomaterials are stabilized and uniformly dispersed in a liquid such as water using a simple procedure. Methylcellulose is added to hot water where it separates and expands with a temperature of about 80-90 degree Celsius. Methylcellulose swiftly dissolves when the water cools down. Carbon nanomaterials are dispersed in a solvent and sonicated. This nanomaterial dispersed solvent is then added to the methylcellulose dispersed water and mechanically stirred. The resulting uniform mixture is up to 90% by weight nanomaterials and is stable for months.
