NOVELTY - Dye is prepared from graphene oxide. USE - Dye for producing outdoor products such as polyurethane material, and sports clothing. ADVANTAGE - The dye enables to prepare polyurethane material that has good antibacterial property and good moisture permeability. The sweat produced by the human body can quickly evaporate that results in increasing the wearing comfort. It adapts to changes in the market and people's needs, and has improved product grades and added value-added products. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing dye, which involves placing 2.5 wt.% graphene oxide solution in 0.5 g GZG-120 and reacting the mixture at 85 degrees C for 2 hours; and stirring the reaction, reducing the temperature to 25 degrees C overnight and precipitating the product with double distilled water for 72 hours to obtain the desired product.
